I'm not entirely sure where this question should be posted. I haven't found mention of it myself elsewhere.
On the community page (http://www.waze.com/community/) It seems that Canada is completely disregarded under 'Recent Map Problems'. The drop-down provides states but no options for any Canadian provinces (or even the entire country). I'm very interested in helping Waze with maps for my area and with a community in general but I keep getting the unsettling feeling that Canada is just treated as an after-thought.
I realize that much of the Maps and information within Waze is community driven and I am happy to be part of that community and to help any way I can, but many of these type of changes can only be made by the developers. And I can only assume it's a lower priority due to the lack of users in Canada by comparison.
