The rules in Alberta
Alberta's OHS Code requires certified workers for asbestos removal, and anyone planning asbestos removal, or demolition or renovation of a building containing asbestos, must notify Alberta OHS at least 72 hours before starting.
Whatever the rules, don't sand, cut or remove suspect material yourself before it's tested.
Testing and labs
A trained assessor takes small samples, and an accredited lab analyzes them; plan on about $50–$150 per sample. Asbestos labs in Canada are typically accredited under NIST's NVLAP program.
