refugee claim denied

[Isaac7]

I made a refugee application in Canada but I got a letter saying that my application was denied because I had previously applied to the refugee in the United States,
I would like to know what options I have to appeal and get more time in Canada because this October I am planning to marry my partner, she is a Canadian citizen
