Choosing the Right Contractor Matters
A deck is a significant investment—often $10,000-$50,000+. The right contractor delivers a beautiful, safe structure that lasts decades. The wrong one? Headaches, repairs, and regret. Here's how to choose wisely.
Essential Credentials to Verify
1. WSIB Coverage
Why It Matters: Workplace Safety and Insurance Board coverage protects YOU if a worker is injured on your property.How to Verify:
- Request clearance certificate
- Verify at wsib.ca
- Must be current, not expired
Red Flag: Contractors who claim they "don't need WSIB" or are "covered under other policies."
2. Liability Insurance
Minimum Required: $2 million general liabilityWhy It Matters: Protects your property if the contractor causes damage.
How to Verify:
- Request certificate of insurance
- Call insurance company to confirm policy is active
- Ensure it covers the type of work being done
3. Business Registration
Check For:- Registered business name (search Ontario's business registry)
- HST number (indicates legitimate business)
- Established business address (not just a PO box)
