Next thing, before considering the QMS - which is important - is to make sure the folks that design and are charge of the field operations are well versed in the Codes. Canada uses a common National Code which makes that both easier and more difficult.
Also, make sure any products used in the construction if you get the contract are approved by organizations such as ULC, SCC, Certiwood, and others, as then you can know about the products and how they will perform.
Watch the inspection requirements if any under the Codes!
All this needs to be taken into consideration to develop your proposal.
The reason for all this is simple.....if the Code and Code Officials have issues with the construction, any QMS you may have is irrelevant.....
Hope this helps.....
