Radon testing in Ontario
Testing listings hold a C-NRPP measurement credential (CRT). Mitigation listings hold a C-NRPP mitigation credential (CRMT).
92 current C-NRPP testing credentials whose official record names a city in Ontario, ordered by that city. This is partial coverage of professionals with an address on file, not a list of everyone who serves the province or territory.
A C-NRPP certification is not a provincial licence. Confirm the credential and ask whether the professional serves your building before hiring. Check a C-NRPP number.
