Tdogmom, a fairly regular poster on this forum, has a butterfly website with lots of information on monarchs.

Thank you that was very informative, exactly what I was looking for. I think I will give it a try! Any tips on when I should start looking for eggs? Do they even lay them this far North? OH dear I will have a millions questions. Sorry in advance.

Monarchs make it to Canada so you are in their range. I would not bother looking for eggs/cats until at least June. When looking, concentrate on the upper third of the plant, especially the top leaves when looking for eggs. Most of the time, eggs and cats will be on the underside. Monarchs seem to prefer to lay eggs on younger plants so if you are out looking and see a milkweed that is 3' tall, make sure to look at it. The link below is a pic from Monarch Watch on their Facebook page. I don't know if it will work if you are not on Facebook.
