Is Poly B banned in Canada?
The straight answer
No. It was removed from the National Plumbing Code for new work in 2005, but codes are not retroactive: existing Poly B is legal to keep. Production ended in 1998 anyway.
The longer version
No, banned is the wrong word: it was removed from the National Plumbing Code as an accepted material for new installations in 2005, and codes are not retroactive, so existing systems are legal. The pressure on Poly B homes comes from insurers and age, not the law. The codes chapter has the timeline and what it means for renovations.
