This study measures how far Canadians live from a business certified to fix radon, called a mitigator. It reports the share of people within 25, 50 and 100 km of the nearest mitigator’s office, for every census division, every province and Canada. It is the Index’s own data, built from three public sources.

Every certified business is counted, free
We count every business with an active C-NRPP credential, from C-NRPP’s public directory. Payment, claiming a listing or a badge never changes a count.
The data comes partly from C-NRPP’s directory. Until C-NRPP clears reuse, the study’s data carries no licence statement.
