I am a failed refugee claimant. Can I stay in Canada if I marry a Canadian citizen or a permanent resident of Canada?
Being in a common-law relationship with, or married to, a Canadian citizen or permanent resident does not guarantee that you can become a permanent resident of Canada.
As a failed refugee claimant, you can apply to be a permanent resident under the public policy relating to the Spouse or Common-law Partner in Canada Class if you meet all the requirements and you are not inadmissible to Canada.
