Canadian National Master Construction Specification

 

Important information about the Canadian National Master Specification

From 2015 to March 2020, the National Research Council of Canada, with funding support from two departments, has maintained the Canadian National Master Construction Specification (NMS) on behalf of the Government of Canada. While we work to determine future funding, updates and maintenance of the National Master Specification (NMS) are suspended.

We recognize the value of the NMS to Canada's construction sector and governments, and continue discussions with our federal partners about the potential for a continued and enhanced NMS platform. Meantime, you may continue to access the current version of the NMS through our publishers. If you have any questions, please contact us.

The National Master Specification (NMS) is the most comprehensive master specification in Canada, serving as an easy-to-use framework for writing construction project specifications.
