Why Two Provinces Can Read the Same Model Code Differently

When a province adopts a national model code, it doesn't have to adopt it word for word — provincial amendments can add, remove, or modify specific provisions to reflect local conditions, existing regulatory structures, or just a different policy choice on a given requirement. The result is a provincial code that shares most of its structure and language with the national model but isn't identical to it.

This is why comparing a requirement across two provinces by assuming "they're both NBC-based, so it must be the same" is a common and understandable mistake. The safest approach is always to check the specific provincial code text and any of that province's amendments, rather than reasoning from the shared national baseline alone.
