Ontario questions
Do I need a permit for repairs in Ontario?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Ontario Building department.
Is a slab leak covered by insurance in Ontario?
Many policies cover the water damage and access costs from a sudden slab leak, but not the pipe repair itself. Report it quickly and keep photos and the plumber's findings.
