Radon companies by municipality
Last updated: By RadonIndex Research Team
RadonIndex tracks 35 Greater Toronto and Hamilton Area radon companies. 23 of them publish a street address, across 11 municipalities. Radon is a small trade, so most of those hold one or two companies, and only the 2 with enough listings to be worth reading get their own page below. The remaining 12 publish no address at all and are in the category lists instead.

Denser, older neighbourhoods and the larger municipalities tend to list the most companies.
