Hello,
It is best, as others have suggested, and as you have already concluded, to perhaps seek advise from a professional.
If you and your spouse lived together in Canada (in your same address/building/home) and then your spouse later on was accepted to a College and had to live in a different city due to the College being in a different city, and if you have been providing her with monetary/financial support (that you can prove that you are doing) while she has been in College, then it would make logic sense that perhaps CIC may reconsider their decision, since it's a unique set of circumstances. I don't know if this was your situation, but if it was, it probably can be reconsidered by them. It's up to CIC and rules. But at the end, seeking professional advise is best.
Best of luck to you.
