kryt0n said:No. However for the most part lawyers know very little in common law status (except spousal sponsorship). Right now you need to demonstrating 12 months of common law status. It does not have to be immidiately before the application is sent in. You just have to prove at some point you lived with your spouse for 12 months. That's CIC rules.
Damn, I just check the effective date of our marital status in CRA, one shows 2014 January and the other one shows 2015 January
