Housing stock in Ontario
51% of roughly 54,951 housing units predate 1980, and 43% of occupied homes are rented. Age of stock matters for water losses because older assemblies dry more slowly and older supply lines fail more often — and tenure matters because who pays for remediation turns on it. Who pays →

Ontario restoration: common questions
How many restoration firms are there in Ontario?
We hold verified credential records for 7 firms in Ontario. That is a count of what we could verify, not a count of every firm operating here — a firm we hold no record for is simply one we could not check.
What are Ontario restoration firms certified in?
The credentials most often on record here are AMRT (Applied Microbial Remediation Technician, 5 firms), FSRT (Fire and Smoke Damage Restoration Technician, 5 firms), WRT (Water Damage Restoration Technician, 5 firms), ASD (Applied Structural Drying Technician, 4 firms). Each was checked against IICRC's own registry rather than the firm's marketing.
Does Ontario require a licensed mold contractor?
California runs no mold-specific licensing programme — only five US jurisdictions do — so there is no state mold licence to check here. General contractor registration may still apply to rebuild work. IICRC certification is the credential a homeowner can verify, and it is what every listing here is checked against.
Is older housing a factor in Ontario?
51% of Ontario's roughly 54,951 housing units were built before 1980, and 5% before 1940. Older stock more often carries galvanised or cast-iron supply lines, cavity constructions that dry slowly, and materials that predate modern vapour control — which is context for a water loss, not a prediction about any particular building.
