The Permit Process in Toronto
Bathroom renovation permits in Toronto are submitted through the city's online portal with drawings showing existing and proposed conditions. Processing typically takes 10–20 business days. Inspections are required at rough-in stage before walls are closed. aMaximum Construction manages the entire permit process for clients.
What Happens Without a Permit?
Unpermitted plumbing and electrical work can be flagged during a home inspection at resale, requiring disclosure or remediation. Insurance claims for water damage in areas with unpermitted work may be denied. The permit process exists to protect homeowners — it's always worth doing correctly.
