I tried a few times and this is what is happening.
If the first country I select is Canada then regardless of the province I select the checkout will not continue to the credit card info.
If I then select United States and a state (say Florida), then it will immediately ask for credit card info.
If then I choose "change address" and select Canada and any province, it will proceed however it will still maintain the selected stated (ie Florida) within the address rather than updating it to the selected province.
