In Ontario, many exposure claims begin informally:
- A worker notices headaches, coughing, or rashes after a particular shift.
- A renter or visitor reports strong odors or irritation after maintenance, painting, or HVAC issues.
- A nearby site (worksite dust, demolition, or remediation) changes air quality—and symptoms follow.
The problem is that early symptoms are easy to dismiss, and early evidence is easy to lose. By the time you seek care, you may have already missed the chance to document timing, environmental conditions, and the specific substance involved.
Your legal team’s first job is to build a timeline that makes sense medically and legally—using AI to organize information quickly, while keeping the final decisions grounded in verifiable records.
