Preface

The National Plumbing Code of Canada 2020 (NPC), together with the National Building Code of Canada 2020 (NBC), the National Energy Code of Canada for Buildings 2020 (NECB) and the National Fire Code of Canada 2020 (NFC), has been developed by the Canadian Commission on Building and Fire Codes (CCBFC) as an objective-based national model code that can be adopted by provincial and territorial governments.

In Canada, provincial and territorial governments have the authority to enact legislation that regulates the design and installation of plumbing systems within their jurisdictions. This may involve the adoption of the NPC without change or with modifications to suit local needs, and the enactment of other laws and regulations regarding plumbing system design and installation, including requirements for professional involvement.

The NPC is a model code in the sense that it helps promote consistency among provincial and territorial plumbing codes. Persons involved in the design or installation of plumbing systems should consult the provincial or territorial jurisdiction concerned to find out which plumbing code is applicable.

This edition of the NPC succeeds the 2015 edition.
