Yes one of my friend did that and everything went smooth I believe they call it Fiancée Visit.I think the best option is as mentioned by @Baha.A.T , kudos to you brother. Go ahead with a visiting visa with all necessary proofs of tie, and then, consummate the marriage and get the certificate and use same to include her in your PR application. But as someone rightly mentioned above, the IRCC ought to know that the major reason for a spouse coming to see a partner is ultimately for them to cohabit perpetually? May God help us.
