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. 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 get warmer.Where to buy factory paint?
Take an old paint chip and take it to canadian tire store. compare the old paint to';near match'; paint spray can. Or you can go to any body shop to get the original paint mixed for you but you need a spray gun and an air compressor. With the near match paint, you can't really tell the difference unless you look at it closely.Where to buy factory paint?
How old is the car? If its older then a couple years the original code is useless because the paint fades over time so you have to match the paint as it is now.
Your best bet is to take a small paint chip from the car into a dealership to have it analyzed. They should be able to order the paint for you. Hope that this helps. Good luck.
