If you were approved with only the information and documentation you provided, it is unlikely the CIC would require them to evaluate your spouse's PR application. Still, it's a good idea that you get your tax documentation taken care of in order to comply with Canada Revenue.
The documentation/information critical for your spouse's PR approval will be other things, such as proof of relationship to you (marriage/common-law documents, photographs, affidavits from family, etc.), police clearance records, and proof of having cohabited.
Thanks Aneyshar. I hope you are correct. And yes, I will get cracking on those old tax returns.
