I'm Canadian and have found the same, most restaurants are willing to work with GF and other allergies. As with anything, some are more educated on the subject and risks than others. Moxie's, for example, has had the manager come out each time I go in so they can be sure what I'm ordering is safe and the manager has supervised preparation. Montana's has an allergy guide online that includes gluten/wheat allergy and others to help but remember to talk to your server as well about it because changes can be made and not listed online. I only had one bad experience there (out of a dozen) early in my GF days when the server insisted the gravy and cornbread were safe for me and rather than argue further, when the food arrived WITH the cornbread on the plate, I just removed it and ate around where it sat. Now I know better than to do that.
A lot of restaurants have their info online these days but some you have to look way at the bottom to find a link to allergen or nutrition guides.
Hope that helps!
