Where to buy factory paint?

I wanted to know if you guys know where is a good place to get factory matched paint? Preferably in an aerosol can. I have a 1991 Astro and my paint code WA9658. i saw a couple good websites, but they don't ship aerosol to Canada. I'm going to be doing some rust repairs when it gets warmer. But i don't know where i cant get matching paint in Ontario.
Any help would be appreciated!
Thanks!

As long as you got the paint code. The paint store will match the color.

Right, If I'm right you can't really get "OEM" paint.
Which is why no color will ever be a perfect match.
Because different companies mix differently, painters vary, gun settings vary etc...
Black however, does not have that problem.
