I do live with frost, and with our chinooks, there are probably more freeze/thaw cycles than normal. A couple of you mentioned problems with being in Canada and in frost zones. Is this because of the moisture that sits in the clay soil that is expanding and contracting with freeze/thaw?
You definitely want to dig more than 4 inches for your concrete. You are basically in the same zone as where we are, and you must have at least 10 inches of good granular stone preferably clear, with wiremesh and I would use minimum 4000 PSI with air. Best thing you can do is call the concrete supplier he will tell you automatically what needs to be done in your area that will be your best advice
