Hi Kevin, Where is your Mexican village located? Are there monarchs in England? I think that monarchs and the migration process is such a fascinating occurrence. About your question....I do know that monarchs migrate up into Canada, although I don't know how far up into Canada they go. I was camping up in northern Minnesota and actually saw monarchs in Thunder Bay which is an area just on the Canadian side of the border. The monarch lays its eggs in the summer in Minnesota once the milkweed has bloomed (which takes a while because it is so cold). Around July is when I really started to notice them this summer. I would think that they emerge in Canada about a month later than they do here, but that's just a guess. Good Luck on your project. -karen
