Hi.
Welcome to the boards and welcome to model building.
First off, being a fellow Canadian, I'll say that the best spray paints that won't kill your model are Tremclad spray Enamels.
Both my father and I have won many model car contests with vehicles painted in Tremclad.
Although the colour sellection isn't the broadest, they still have the important colours like Red, Navy Blue, Sky Blue, Black, White, ect. There's even Aluminum and Clear, although I find that the Aluminum doesn't have a good drying time.
They cover really well and can result in vibrant colours.
I've used them since the earily 1990's and they are as good now as they were when I first started.
The beauty of Tremclad is that they are readily avalible at Wal-mart, Home Hardware, Home Depot, Rona, even Zellers!
It's strange that you would say that Testor's paints are hard to find in Canada.
I own Monster Hobbies in High River, Alberta and I carry Testor's along with the 35 other hobby shops in Alberta.
I could see that if you bought your model in a Wal-mart that you might have difficulties finding Testors as most Wal-Marts model sellection seem to be down to a small shelf in their toy isle, but try looking in your phonebook for a hobby shop in your area.
If you can't find one, I'd be more than happy to help you out. Check my store web site :

Good luck and if you can post your finished kit, we'd all be happy to see it!
Sincerly,
