I want to use a dropshipper company for our entire catalog within Canada (only) and ship from our main location (US) to everywhere else.

I'd prefer to use UPS rates (with live quotes) for both Canada and US (but from different shipping locations), Canada Post within Canada, and USPS within the United States.

Is it possible to configure this out of 1 store? I've tried to find the answer to this, but after a week of searching, I'm coming up a bit empty-handed.

Thanks.
