Marriage post COPR for both - What to do in such a case?

[CANPRI]

Hi,

I have submitted my application on 15th Nov. My boyfriend's application will be submitted by Dec mid.

Our marriage is getting fixed in June 2018.

My Medical is valid till 14th October 2018.

Assuming that we both get copr by March or April 2018 and we get married and intimate cic by July 2018 (After receiving marriage certificate), would this be much of a hassle?

Please help!!!
