Hi Jeff!
I am not an expert on MT programs (I don't even act or sing, haha), but I can tell you that there are many reputable programs in the US. If you want to come here, you should. Check out collegeboard.com, and there is a message board related to musical theatre programs in the US. You should apply to Sheridan, if you like, as a backup, but you'll have no problem finding a good program in the US.
Random, but Eryn Murman (Spring Awakening understudy/ensemble) is a Sheridan graduate!
