if yr lady is froma visa exempt country. then she can travel to canada and u guys can get marreid , if she is not from a visa exempt country, then she has to apply, chances in this situation are very slim and again each case is individaul and on different merits.. also if she is not from a visa exempt country, then try n go to her country and marry her and what u can do is come back and do the sponsorship.
the proof of relationship is yr burden so when u doing the application u have to provide enough evidence to proof the geniuness of your marriage..
good luck..
