In Markham, chemical exposure often happens in situations that don’t always feel like “industrial accidents” at first. Many cases begin with events tied to:
- Maintenance and remediations at commercial properties and mixed-use buildings
- Construction and trade work where solvents, adhesives, sealants, degreasers, or cleaning chemicals are used
- Suburban home remediation after spills, water intrusion, pest treatments, or “quick-fix” cleanup attempts
- Warehouse and loading-area incidents where ventilation, storage, labeling, or PPE can be overlooked
Symptoms may appear immediately—or show up later. People sometimes assume it’s “just irritation” or a temporary reaction until the effects worsen. That delay can create confusion about causation, especially when the responsible party tries to blame normal sensitivity, poor ventilation, or “misuse.”
