Replying to I have a 600 dollar credit for Air Canada

I canceled a flight last summer, but didn't know till now that I have until June to use the credit from the flight. I'm in Denver, and can only fly Air Canada, So I pretty much have to fly somewhere in Canada. Any suggestions. I could go to Toronto to visit family, but I was maybe thinking summer skiing too. For reference, I'm 20, so I could drink there. And I grew up in Ontario, so if I went there, It would just be to visit, not check it out. But I've only been to the west coast when I was really young, so that could be cool.
