National Physician's Day
2026-05-01
National Physicians’ Day in Canada is celebrated annually on May 1st. In 2026, this day falls on a Friday. It honors the birthday of Dr. Emily Stowe, the first female physician to practice in Canada, recognizing the dedication and care physicians provide to patients and the healthcare system.
Says the Canadian Medical Association: “In an era where Canadians are bombarded daily by information both real and fake, they continue to place the highest trust in doctors to provide quality health information and evidence-based care. Year-over-year trust in doctors remains exceptionally high providing much needed stability amidst a changing landscape. Doctors’ voices matter and are needed more than ever.”
Key Details for 2026:

National Physicians’ Day: Friday, May 1, 2026. This day, marked by the Canadian Medical Association (CMA), celebrates all Canadian doctors.
Purpose: To express gratitude for doctors’ commitment to patient care, particularly following challenges like the COVID-19 pandemic.
Provincial Celebrations: Many provinces, including Ontario, formally recognize May 1st for this purpose, with landmarks often lighting up in blue.
Actionable Appreciation: The Ontario Medical Association (OMA) and others often encourage thanking doctors through social media using #DoctorsDay.

Construction Safety Week
2026-05-04 08:00 - 2026-05-08 17:00
RECOGNIZE • RESPOND • RESPECT
Construction Safety Week has long been a powerful show of force, a catalyst for bringing the industry together and putting a spotlight on the critical importance of health and safety. The construction industry represents one of the largest employment sectors in the world—and with that scale comes immense responsibility, and opportunity.
Over the last decade, we’ve made meaningful strides: advancing best practices, transitioning from hard hats to helmets, shedding light on vital issues that affect health and safety, like mental health, fostering a culture of care and accountability, and creating partnerships and initiatives for improving jobsite safety. See Website

FROM OHCOW
The Silica Control Tool
Save Lives and Preserve the Health of Workers
Construction Workers are at high risk of illness as well as injury. Research has proven the harmful and sometimes fatal effects of crystalline silica, a very fine dust that can cause respiratory illness and cancer when inhaled. This dust is present when construction materials such as glass, concrete, asphalt, and other substances are grinded, sawed or crushed.
If there is even a chance that workers are being exposed to silica dust the FREE Silica Control Tool should be in use. For more information on who is at risk, and links to free registration for the Tool, check out our web page. The tool is available in French and there is a version created especially for surface mining. Go to SCT Page
Hand Arm Vibration (HAVS)
Hand-arm vibration is the transfer of vibration from a tool or workplace to a worker’s hands or arms. It is common for construction workers who handle drills and other heavy hand-held equipment.
The level of hand-arm vibration is determined by measuring the acceleration of the tool or object grasped by the worker. It effects the the circulatory, nervous and musculoskeletal systems of the worker and can lead to serious injury.

Signals of Strain: Assessing Psychophysiology in the Real World
SPEAKER: Eddy Madou – Operations Lead CISWP
Description: Psychophysiological measures, which are objective indicators of the interactions between psychological processes and physiological responses, allow us to quantify stress, fatigue, cognitive workload, and well-being. Historically, the extent to which these measures have been validated, feasibly deployed, and linked to the demands of work remains has been unclear. Additionally, recent technological advancements may aid in the practical implementation of such tools in real-world occupational settings. This presentation describes psychophysiological measurement tools and methods suitable for use in occupational settings and their applicability for assessing cognitive and mental demands of work. Findings will inform the development of more standardized methodologies and support best practices for reliable objective psychophysiological assessment in occupational research and practice.

Injured Workers Day
2026-06-01
Every year on June 1st, Ontarians pay respect to the hundreds of workers who have died or become injured while working on their job sites. The Ontario Injured Workers Day is an opportunity to recognize the individuals who have suffered injuries and fatalities as a result of their workplace conditions.
Bill 118, the Injured Workers Day Act
In Ontario, we owe a debt to Sudbury MPP and NDP Labour critic Jamie West, who in 2024 pushed to have June 1 officially recognized as Ontario’s Injured Workers Day. He introduced his Private Member’s Bill, Bill 118, the Injured Workers Day Act, in the Ontario legislature. Because of this Act, June 1 of every year will be formally recognized as Injured Workers Day. See OHCOW page about this achievement.

Brain Injury Awareness Month 2026
2026-06-01 08:00 - 2026-06-30 17:00
Brain Injury on the Job
1. Immediate Action & Reporting

Report the Injury: Notify your supervisor immediately and seek medical attention. Ensure a formal report is filed.
File a WSIB/WCB Claim: Contact your provincial workers’ compensation board to initiate a claim for lost wages and medical coverage. For example, Ontario workers can use the WSIB Mild Traumatic Brain Injury Program of Care for community-based early recovery and occupational support.

2. Returning to Work

Workplace Accommodations: Employers are legally obligated to accommodate recovering employees to the best of their ability. This often involves modified hours, ergonomic adjustments, or reduced workloads.
Planning: Use the Brain Injury Canada Return to Work Guidebook for practical self-assessments, checklists, and strategies on how to transition back to employment successfully.

Opioid overdose and Brain Injury
Opioid overdoses can have catastrophic results, including brain injury. Brain injuries present new challenges and changes that can be difficult to cope with, particularly if the survivor is also trying to cope with substance use.
Drug poisoning occurs when a toxic amount of one or more substances is introduced into the body, a situation commonly referred to as an overdose. Overdose risk is influenced by multiple factors, including the amount of substance taken, changes in substance tolerance, the use of multiple substances (knowingly or unknowingly), and the physiological effects of substances, such as suppression of breathing, consciousness, or other vital functions. Go to Opioid overdose page

In Canada, June is Brain Injury Awareness Month. Each year national, provincial, and local associations run campaigns to increase awareness about the prevalence of brain injury, the obstacles that exist for those with brain injury, and the need for more services and support at all stages of recovery.
This Brain Injury Awareness Month, we are going Beyond the Injury to raise awareness of brain injury and its profound impacts on all aspects of daily life, for individuals and for family/caregivers.
Our goal is to generate more national awareness and understanding of brain injury, and to raise money to continue developing programs and resources that will improve the lives of all Canadians living with brain injury. Go to Brain Injury Canada

The Summer Solstice is a significant marker in many cultures. Being the longest day of the year, it is a “threshold” day holding deep spiritual and cultural significance for many Indigenous peoples.
As mentioned in the document, there is an art exhibition in Windsor entitled Water Protectors Exhibit for National Indigenous Peoples Day featuring work by Indigenous artists.
The document also includes notes about the history of the commemorative day and a link to a map showing events throughout the province, as well as links to Indigenous artists, information about collaborative partnerships, and territory acknowledgements. Ontario is addressing the alarming increase in cancer, diabetes, heart disease and respiratory diseases among Indigenous peoples. A report entitled “Path to Prevention – Recommendations for Reducing Chronic Disease in First Nations, Inuit and Métis”, which is focused on chronic diseases and health inequities in these populations in Ontario.
The report identifies risk factors for these communities as tobacco use, alcohol consumption, physical inactivity and unhealthy diets. The policy recommendations were developed through extensive engagement with First Nations, Inuit and Métis communities, the Government of Ontario and non-government organizations. There was a process for validation by First Nations, Inuit and Métis to ensure the recommendations accurately reflects the priorities of their communities.
The report is a key part of the Aboriginal Cancer Strategy and a companion report to Taking Action to Prevent Chronic Disease: Recommendations for a Healthier Ontario. SEE REPORT

PTSD Awareness Day
2026-06-27
The Public Health Agency of Canada
Public Statement
On National Posttraumatic Stress Disorder (PTSD) Awareness Day, we come together to raise awareness around PTSD, break the stigma, and show support and compassion for those suffering.
Post-traumatic stress can affect anyone, regardless of background or circumstance. Living through a traumatic event can have a profound impact on a person’s mental health, their relationships with family and friends, and their ability to cope with everyday life.
While anyone can develop PTSD, many Canadians are at an increased risk because of the nature of their jobs. Every day, frontline workers, healthcare providers, public safety and military personnel are called into action. They respond to emergencies of all kinds and are routinely exposed to trauma. It is important to learn how to recognize the symptoms of PTSD, as they can vary in intensity over time and from person-to-person.
Those struggling with mental health or substance use issues can find free resources and lists of supports in their area at Canada.ca/mental-health.
Canadian Mental Health Association (CMHA)
PTSD is a mental health condition triggered by traumatic events like natural disasters, accidents, war, or assaults. Symptoms include unwanted thoughts or dreams, physical responses, strong negative emotions, and loss of interest in activities. A person with PTSD could experience the event themselves or witness it happening to others. If you’re struggling, please reach out for support. CMHA Page

Uterine Fibroid Awareness Day
2026-07-21
What are Uterine Fibroids?
Uterine fibroids are a common non-cancerous tumour of the uterus. A non-cancerous (benign) tumour is a growth that doesn’t spread (metastasize) to other parts of the body. High levels of the hormones estrogen and progesterone increase their growth, as well as chemicals that mimic female hormones. In most cases, fibroids are extremely small and barely noticeable. They should be monitored as they can expand in size over time and in some cases lead to infertility, chronic pain, and cancer.
Occupational Risks and Fibroids
Reproductive health issues are usually not work related. However, exposure to metals, solvents, pesticides, radiation, viruses, and extreme stress are all factors that can effect reproductive health. Xenoestrogens are foreign, man-made chemicals that mimic or disrupt natural estrogen and are found in plastics and other everyday substances present in our environment. In some production facilities and business prolonged exposure to chemicals has been linked to fibroid tumors, reproductive issues, endocrine imbalances, and hormone-dependent cancers. Published research such as this paper from Chinese researchers has indicated evidence that such chemicals can be airborne. Job areas where exposures to EDCs (Endocrine-Disrupting Chemicals) may contribute to reproductive health problems:

Cosmetology & Hairdressing: Certain chemical hair relaxers and dyes pose risks. Research suggests prolonged exposure to EDCs in these products may elevate fibroid or endometriosis risk.
Manufacturing & Industrial Work: Workers in plastics manufacturing, textile production, agriculture, and commercial cleaning often have elevated levels of EDCs in their bodies.

The Canadian Centre for Occupational Health and Safety (CCOHS) has a web page on reproductive health as it relates to workplace conditions. In addition to chemical exposure, research has revealed the stress caused by regular night shift work can disrupt the endocrine system and lead to tumor growth and even cancer, especially in women.

Exposure to industrial solvents, pesticides, and plastics/BPA can interfere with hormone signaling, which is linked to an increased likelihood of developing fibroids.
Workplace exposure to heavy metals such as cadmium and lead has been associated with adverse uterine health. [1]
High-stress occupations and chronic sleep deprivation (e.g., rotating night shifts) can trigger hormonal imbalances and exacerbate the pelvic pain and heavy bleeding associated with fibroids. According to current research published in Biomedical Reports, the International Journal of Environmental Research and Public Health and other sources, night shift work is the leading work-related factor that increases the risk for reproductive health issues and cancer.

The Workplace and Reproductive Health
OHCOW professionals and staff have experience investigating workplace conditions that point to increased health risks, including hazards to the reproductive system and organs. If you think workplace conditions may have caused your fibroids or other reproductive health issues, contact us.

Self Care Day
2026-07-24
Self-care is the ability of individuals, families and communities to promote health, prevent disease, maintain health, and cope with illness and disability with or without the support of a healthcare provider – World Health Organization. Self Care Canada Self Care is paying attention to physical and mental health, as well as environmental and emotional factors that may sometimes be neglected in the course of busy lives. It can mean getting exercise, eating nutritious food, and taking breaks.
Career Professionals of Canada warns that “job demands can sometimes impact our well-being.” They promote strategies to prevent burnout, including setting boundaries, realistic expectations, self-compassion, taking breaks and stress management techniques. they offer coaching courses that promote self care, because such strategies benefit individuals and organizations as a whole.

From the CHMA: With the majority of Canadians working between 35–45 hours a week—roughly one-third of their livesi —self-care is essential in the workplace. Organizations that encourage employees to practice self-care have reduced turnover, increased employee engagement, enhanced creativity, and a more resilient workforce capable of navigating challenges effectively. CMHA’s Not Myself Today program helps employers and employees foster a safe and supportive wok culture while building greater understanding and awareness of mental health and reducing stigma. Not Myself Today Website According to the International Self-Care Foundation, Self Care is comprised of pillars:
Pillar 1: Knowledge & Health Literacy
Pillar 2: Mental WellBeing
Pillar 3: Physical Activity
Pillar 4: Healthy Eating
Pillar 5: Risk Avoidance & Mitigation
Pillar 6 Good Hygiene
Pillar 7 Rational & Responsible use of Self-Care Products & Services

As part of the 2023 Mayday, Mayday Webinar Series, the topic of Youth Mental Health was explored. The webinar acknowledged that young workers have recognized vulnerabilities to workplace injuries & harms, including to psychosocial risk factors, made worse in the pandemic.
The presenters spoke of the need to learn more about challenges faced by these frequently exposed front-line staff in their daily jobs, and some solutions to reduce risk and mitigate harm from an agency, industry and advocacy perspective.
Moderated by OHCOW Ergonomist Melissa Statham, it featured two parts:
Part A: Youth Mental Health Outreach/Support, challenges and solutions, Ashleigh Erdelyan MSW RSW, Zahra Abou Elhassan MSW RSW, Youth Wellness Hub, CMHA-Windsor Essex

International Overdose Awareness Day
2026-08-31 08:00 - 17:00
25 Years On. Still Needed.
Every August 31, International Overdose Awareness Day (IOAD) brings a global community together to take action on overdose. Hold an event, spread the message, take action today. This year the theme for IOAD is 25 Years On. Still Needed. For 25 years, International Overdose Awareness Day has brought people together to remember those we’ve lost and to take action to save lives. Go to Site
Studying the Problem
The Institute for Work and Health conducted an extensive study on Opiod use among Ontario workers. They explored which professions were at greater risk for opioid use and overdose. See the information here.
A Data Tool
The IWH and the Ontario Cancer Research Centre partnered to create The Opioid-Related Harms among Ontario Workers project. This project aims to establish a surveillance program to monitor opioid-related adverse health events among Ontario workers.
The Opioids and Work Data Tool is an interactive tool that illustrates patterns of opioid-related harms among Ontario workers. The tool includes three dashboards, each displaying data for a different opioid-related harm identified in emergency department and hospitalization records:

Poisonings
Mental and behavioural disorders
Adverse reactions

Graphs within each dashboard can be customized to show trends in opioid-related harms over time, as well as the characteristics of the workers experiencing these harms (i.e., their age, sex, health region, occupation, and industry).

Opiod Use at Workplaces

Opioid and substance misuse in the Building Trades: A strategy to deal with an epidemic.
Speaker: Carmine Tiano, MA, Director of Occupational Services, Provincial Building and Construction Trades Council of Ontario
Carmine covers factors in the construction industry that make its workers vulnerable to substance abuse and addiction. Workers usually work contract on different sites, sometimes for short periods of time, and are always adjusting to new work sites and conditions. Work can be dependent on weather and project progress. He explains how accepted accident stats are skewed and don’t show the whole story, and how the compensation landscape does not adequately support injured workers.
Opioid-harms among Ontario Workers, what we know and are striving to learn.
Speaker: Dr. Nancy Carnide, PhD, Associate Scientist, Institute for Work & Health
Dr. Carnide discusses the statistics for OPIOID harms among Ontario workers. Opioid uses has increased since the Covid pandemic, and males are most effected. In Ontario, there are not adequate statistics gathered or surveillance systems to monitor substance abuse in workplace — BC has better records. In that province, construction, transportation and warehousing are the topic fields where opioid abuse and fatalities occur. 44% of those who died from overdose were employed at the time of their death. Get factual information about the real numbers from this webinar.

Ovarian Cancer Awareness Month 2026
2026-09-01 08:00 - 2026-09-30 17:00
Current Research Findings
According to the Canadian Cancer Society:

Ovarian cancer can start in the cells of an ovary, but the most common type is thought to start in the cells of a fallopian tube. Fallopian tube and primary peritoneal cancers are staged and treated the same as epithelial ovarian cancer.
Risks for epithelial ovarian cancer include having a family history of ovarian cancer and BRCA gene mutations. Fallopian tube and primary peritoneal cancer share many of the same risks as epithelial ovarian cancer

After a Concussion: Return to Work Strategies

According to Parachute Canada, Canada’s national charity dedicated to injury prevention, returning to your regular activities, including work, after a concussion is a step-wise process that requires patience, attention and caution. In the Return-to-Work Strategy: • Each step is at least 24 hours. • Move on to the next stage when you can tolerate activities. • It is common and OK for your symptoms to worsen mildly and briefly* as you return to activities. But, if your symptoms worsen more than this, take a break and adapt activities.

Occupational Risks
Genetic factors and lifestyle pose the biggest risks for the occurrence of cancer. Environmental and Occupational risk factors are also a huge factor. According to peer reviewed articles in the Journal of Cancer Prevention and other sources, the most at risk are

farmers/agricultural workers: pesticides
some manufacturing such as rubber workers: chemicals such as carbamates and triazines, cadmium, chromium, cutting fluids, acrylonitrile
construction work, whole body vibration
flight personnel, health workers, security: shift work
ionizing radiation
