GBD, it's not Mobil, but check out this oil:

Check out all the approvals. It has superior specs to the Mobil, and it might be available in Canada. I will be using this oil once my factory oil changes cease.
Edit: These guys sell it (I've bought from them), you'll have to check to make sure they will ship to Canada:
