In order to help people, free and widely available maps are a good tool to rescue parties.  Many users of OpenStreetMap have organized a wiki page to manage the work that needs to be done to quickly improve OpenStreetMap for this part of the world. Thankfully, Yahoo has high resolution imagery of the region making it possible to trace the streets.  Note: remember that only Yahoo imagery can be used, as OpenStreetMap has a signed derivative work permission with Yahoo.

If you know how to edit maps, maybe you can land a hand! CrisisCommon also has other resources.

Follow-up: Mikel Maron has before and after images along with more info.

Really? Please don’t. It might sound like a good idea to fall back on the public transportation when you can’t find your car under the snow or when it won’t start. But think of all the regular users, the ones who pay monthly to use it. You are only going to add pressure to an already heavily used network. Its capacity doesn’t increase on snow days!

I already have problems finding a place when going on at Métro St-Laurent, how many trains will I have to wait to find one on snow days?

Why should I be the one waiting while this is my chosen transportation method? I chose to use an ecologic and weather proof transport. Did you? if we were all using the public transporation everyday, we’d have a much better network.
