    If you or someone you work with is in crisis, you can call or text 988, Canada's Suicide Crisis Helpline, any time, in English or French. For confidential help with alcohol or drugs specifically, the Canadian Drug and Alcohol Helpline is free and open 24/7 at 1-800-565-8603, and it connects you to local treatment and support. If you are an Indigenous person, the Hope for Wellness Help Line at 1-855-242-3310 offers culturally grounded support. None of these calls go to your employer, your union or your licensing body. Reaching out is the move that keeps people alive and keeps people working.‍‌​‌​​‌‌‌​‌‌​​​​​‌‌​‌‌​​​​​​​​​​‍

    The reality in the trade

    Substance use is a serious issue in construction, and it is usually a coping response, not a moral failing. Chronic pain, hard physical work, long days, time away from home and a culture that normalises a few drinks to wind down all push in the same direction. Canada is also living through an opioid crisis driven by an unregulated, often fentanyl-contaminated drug supply, and Public Health Ontario has found that construction workers are over-represented among opioid-related deaths in the province. The point is not to shame anyone; it is that this is common, it is dangerous, and there is a way out that starts with a phone call.

    Naloxone: the toolbox reality

    Naloxone is a medicine that temporarily reverses an opioid overdose. The nasal-spray kits are simple to use without medical training, and having one on site can be the difference between life and death.

    • In Ontario, naloxone kits have been mandatory on many construction sites since June 1, 2023, where an employer has reasonable grounds to believe a worker may be at risk of an opioid overdose. At least one trained worker must be on site during operating hours.
    • Across the country, free take-home naloxone kits are available at most pharmacies without a prescription. Even where it is not legally required, carrying one is sensible.
    • Have a plan: know where the kit is, who is trained, and who calls 911. The wider distribution of naloxone is one reason opioid deaths fell in 2024.

    Recovery: there is a path, and it works

    Help is real, it is often free, and it does not have to mean stopping work.

    • Canadian Drug and Alcohol Helpline: 1-800-565-8603, 24/7, for confidential referrals to local treatment.
    • Your provincial health line (often 811) can connect you to addiction services and counselling near you.
    • Your EAP. If your employer or union runs an Employee Assistance Program, it usually includes confidential counselling and addiction referrals, separate from your boss and your record.
    • Opioid Agonist Therapy (OAT). Treatments such as methadone and buprenorphine-naloxone (Suboxone) are proven, prescribed by a doctor, and covered by most provincial drug plans.
    • Supervised consumption and overdose prevention sites in many cities offer a safer, monitored option and a bridge to treatment.

    Helping a workmate

    • Lead with concern, not judgement. "I've been worried about you" opens a door that "sort yourself out" slams shut.
    • Know the numbers. Have 988 and 1-800-565-8603 in your phone, and offer to make the call with them.
    • Carry naloxone and know how to use it. It is a 5-minute thing to learn and it saves lives.
    • Do not work impaired, and do not cover for impairment on site. Safety comes first; support and safety are not opposites.

    Common mistakes

    • Treating it as a discipline problem. Punishment drives use underground; support and non-punitive policies are what actually reduce harm and deaths.
    • No naloxone on site. Even outside Ontario's rule, an overdose can happen on any site. A free kit and one trained person is cheap insurance.
    • Self-medicating pain or stress alone. Alcohol and drugs make the underlying pain or mental-health struggle worse over time. There are gentler routes in Mental Health in Construction.
    • Staying silent over stigma. Helplines, EAPs and treatment are confidential. The conversation does not follow you to the next job.
