Ditto what Steve said. The only tailors making Argyle jackets I know of are in Scotland. So whether you order from a Canadian retailer, or a US retailor, the jacket will most likely still be made in Scotland. And you are going to have a much easier time finding made-to-measure than true bespoke jackets.

Steve at Freedom Kilts is in BC and can help you. Burnets & Struth in Ontario is another good option.

We are somewhat further south (NC), but still happy to work with you. Our Argyle tweed selection can be found here:
