Ontario TSSA Permit Requirement
Any gas appliance installation requires:
- TSSA permit and inspection
- Work by TSSA-licensed G1 or G2 gas technician
- No exceptions — fines for unlicensed work: $50,000+
- Unpermitted gas work discovered at home sale is a major liability
Chimney Liner Requirement
All new or converted wood/gas appliances using an existing masonry chimney need a properly sized stainless steel liner. Original clay tile liners are often cracked — get a video inspection before relining.
WETT Inspection (Wood Systems)
Most Ontario insurance companies require a WETT certificate for wood-burning fireplaces and stoves:
- Inspects firebox integrity, liner condition, clearances to combustibles
- Required at point of home sale in most cases
- Without WETT certificate: insurance may be refused or rates increased
Surround and Mantle
Gas fireplaces pair with: porcelain tile surround (most popular GTA choice), natural stone, custom millwork mantle. Budget $1,500-8,000 for surround and mantle depending on materials.
