(first of all, I think you should post this somewhere else, if you don't want to get banned).
wow, interesting case. I guess you could look at it from a mature point of view. Is she just visiting Canada, or leaving for ever? Is there a way for you to be together, if it happens (unless you are into long distance relationships, which I don't recommend) and so on.
I'd definitely EXPRESS my feelings for her (not in a whiny way, but in a confident direct way) and say your truth. Expression is one of the most important aspects of confidence and well being. Be confident about what you want. I'll make it even stronger: it's something you SHOULD do

.
Obviously then it's her choice, whether she actually wants to stay with her bf, or get together with you. I honestly think expressing feelings is far more important than the consequences.
The other thing I'm wondering about. why did she leave you this message. Women communicate in subtle ways, so this might have been an invitation for you to be a man and tell her what you feel/want.
Most importantly: follow your heart! (very precise and practical advice heh

)
That's my two cents.
