The Main Trades Required for House Construction

Frequently Asked Questions

How much does it cost to build a house in Canada?

A typical single-family home costs $250,000–$500,000+ CAD depending on location, size, and finish quality. In expensive markets like Greater Toronto Area and Metro Vancouver, costs can exceed $600,000 CAD. Trade costs typically represent 35–50% of total construction expenses.

Do all trades need to be licensed in Canada?

Certain trades - electricians, plumbers, and HVAC technicians - must be licensed and insured in all provinces. Others, like framers and drywall installers, may not require licensure but must follow building codes. Always verify licensing requirements with your province's regulatory body.

What's the best way to coordinate multiple trades?

Hire a general contractor. They manage scheduling, coordinate trades, inspect work quality, and ensure everything runs on schedule and within budget. This coordination prevents costly conflicts and delays.

Can I hire trades directly instead of a general contractor?

Technically yes, but it's risky. You'd be responsible for permits, inspections, scheduling, code compliance, and legal liability. Most homeowners benefit from a general contractor's expertise and accountability.
