do I need to notify CIC about becoming common law if I only applied for WP?

[Lady_Ashka]

I am currently waiting for an extension of my WP (applied in July). In September my Canadian BF and I gained common law status (we've been living together for a year now, etc). I didn't put in common law as my marital status in the application for the permit extension (and put divorced instead, as i am), because I figured common law is defined as 12 months of a relationship. But now that we've notified the CRA (for his tax purposes), I am wondering, should I somehow notify CIC about this relationship status change? My WP application is under consideration, but I have no other applications pending at the minute. And if I should notify them, how do I do it?

Also, is there anyone else I should notify, or fill in some documents somewhere, have some declarations signed? I know that there is a CIC form, a declaration of common law, that needs to be submitted with WP applications, but because we were not yet common law I did not submit it. Do I need to submit it now? And if so, who should I have it signed by (who should be the one administering the declaration?)

We will be applying for my PR in May.

EDIT: for anyone who is wondering about the same thing, I called the CIC Call Centre, finally got through to a consultant, and she told me there is no need to notify CIC about this change now (because it is a WP application). Thanks to everyone who read this!
