Sick Notes for Ontario Construction Workers: Your Rights on Site

Sick Notes for Ontario Construction Workers

Construction workers in Ontario face unique challenges when it comes to sick notes. Between WSIB requirements, union rules, and strict site attendance policies, knowing your rights is essential.

WSIB vs. Regular Sick Notes

WSIB Claim (workplace injury):

• Report to your supervisor immediately


• Visit a healthcare provider (ER, walk-in, or online)


• Your employer files the WSIB Form 7


• Your healthcare provider completes a Functional Abilities Form (FAF)


• WSIB covers lost wages (85% of net earnings)

• ESA protections apply (3 paid sick days, no note required)


• Employer may require note for absences over 3 days


• You pay for the note (unless employer policy covers it)


• No WSIB involvement

Construction-Specific Challenges

1. No desk job alternative — You can't "work from home" with a broken wrist
2. Physical demands — Even minor illness can be dangerous on site
3. Multiple employers — Subcontractors may have different policies
4. Union vs. non-union — Different rules and protections
5. Seasonal work — Missing days during peak season is costly

Your Rights Under the ESA

Even as a construction worker:

• You get 3 paid sick days (no note required)


• You cannot be fired for legitimate illness


• Your employer must accommodate medical restrictions


• Online sick notes are legally valid

Getting a Sick Note Without Losing a Day

Construction workers often work 6am-4pm, making clinic visits during work hours impossible. MedLetter solves this:

• Apply from your phone in 5 minutes


• Receive your note in same day


• No clinic visit, no waiting room


• Available early mornings and evenings


• $49 flat fee

Return to Work Notes for Construction

After an injury or illness, your employer may require a fitness-for-duty note before you return to site. This note should confirm:

• You're medically cleared for physical labour


• Any restrictions (no heavy lifting, limited climbing, etc.)


• Duration of any restrictions


• Follow-up requirements

Union Members: Know Your CBA

If you're a union member (LiUNA, IBEW, UA, Carpenters, etc.):

• Check your collective bargaining agreement for sick note provisions


• Many CBAs require employer reimbursement for sick note costs


• Your union rep can help if your employer violates the policy


• Document everything in writing
