I am sorry that you did not get in. I believe Dalhousie is still open - maybe give it a shot?
If all else fails, try again the next cycle but with more back-up options.
Let us know what your profile is like, maybe we can help give you pointers on where to improve or what admissions might look for.
It's a hard time, but don't beat yourself over it. Chin up, you still got a chance.
