Might check with (input the part number into their search).
They do list the part as “Factory Direct” and utilize a forwarding service for non-USA orders. I have no idea the cost of this service.
Input the part number into a search engine (both with and without the hyphens) to see if you can find it stocked elsewhere. It’s going to be difficult to find given that it’s an obscure part for a discontinued computer.
Another thought would be to contact Sony in Canada to see if they can source the part for you.
