So you went from wanting to come for a vacation to immigrating? Anyway, the only real option is for the two of you to get married/common-law and then he sponsors you.I and my boyfriend just really wanted me to come to Canada for a vacation, just so I could experience the life there with him and meet his loved ones. He had come over to visit me twice and we just wanted to have my turn to do the same. But unfortunately, my travel visas were refused.
So now we've come to the point of giving up the TRV and considering other options for me instead which include immigrating there instead.
Note that you'll have to prove that you didn't get married for the sole purpose of immigrating - the marriage has to be genuine.
