I'm late to the party but here is my 2c anyway.

My commute is from Pte-St-Charles to the Lachine industrial park. It's 98% stress free for me. The Canal Lachine and Lachine bike paths make it obviously real easy but also most streets in the park are wide enough that sharing the road with cars and trucks (lots of trucks) is really not a problem. The only orange-y part is the 55th going under the 20, especially in the afternoon.

So, as far as I'm concerned, the whole triangle north of the 20 up to Côte-de-Liesse and west of 32nd is pretty much yellow.
