Canadian Body trim supply places

So I purchased my 04 Jetta wagon a couple a years ago and I noticed a what was a small rust spot on the driver side door right at the side trim location, over the 2 years the rust spot got bigger and bigger to the point that the car looks like S&%t. I want to remove the trim piece sand and paint the rust spot and reinstall a new trim piece. I am having trouble locating a local place to buy any replacement trim pieces I know it can be purchased online but to buy a $15 trim and have it shipped to Canada it would cost me around $25 - $35 plus exchange. So if anyone knows of a Canadian supplier in the Golden horseshoe area that they can direct me to that would be great.

Can you provide a picture or part number for this trim piece?

Have you tried the local VW dealer?

From a cost perspective, it's probably cheaper and easier to just buy a good used door and repaint it.
