Can individual states modify sections of the National Plumbing Code of Canada?

In the context of the National Plumbing Code of Canada (NPC), individual provinces and territories have the authority to adopt and modify the code to cater to specific local conditions. However, these modifications do not include the ability to delete sections outright. The NPC serves as a guideline, providing minimum standards that ensure safety, health, and performance across the country. Therefore, while states or provinces can adapt certain requirements to better fit their local circumstances or needs, they are required to retain the fundamental sections that uphold the integrity of the overall plumbing system. This ensures a standardized approach to plumbing that prioritizes public health and safety, making it crucial that core elements of the code remain intact.
