Articles on venting:

A very good  article on roof venting is found at Fine Homebuilding Magasine (  While the International Residence Code (IRC) is not exactly the same as the National Building Code (of Canada), the principles described in the article certainly apply.

This is an article from the NRC, which has much of the same information as the Fine Homebuilding article above, but is referenced in the NBC for the venting requirements.

 Asphalt Shingle Class Action Lawsuits and related discussions:

Homeowner information (not limited to Quebec or Canadian sources):

The link below is from the NRCA (National Roofer Contractor Association), a USA umbrella group for roofing contractors, giving advice to homeowners on various aspects of roofing:
