Which rules apply

Ontario Building Code §9.22 (masonry chimneys), CSA B365 (solid-fuel installations), and WETT SITE-Basic scope cover most liner install work. Insurers typically ask for the WETT report post-completion; municipalities ask for permit sign-off pre-cover.

Permit thresholds in Erin

Erin building services generally require a permit for any structural masonry, liner replacement, or new appliance install. Cleaning, cap replacement, and cosmetic work are permit-exempt. Turnaround for over-the-counter permits is usually 5–10 business days.

Certifications that carry weight

WETT SITE-Comprehensive, CSIA CCP or CCS, and WSIB clearance are the three signals adjusters and buyers accept without pushback. HRAI membership adds credibility on venting work.
