Can I do this from Canada?

Yes, you can do it from Canada.
To find a CLEP testing center, go to CLEP Test Center Search to find nearest location and contact information | CLEP
collegeboard.com/clep is a good place to look around.
And for the DSST tests, here's a good site: Free Study Guides and Practice Tests - DantesTestPrep.com
I'm just starting, also, and have 9 credits so far, but I've taken both CLEP and DSST tests at 2 different testing centers.
Good luck!
