I received the email from CIC today asking for additional documents. it is very weird because CIC asks for my spouse's original Option C print for 2014-2016, but both I and my spouse selected "yes" in the question on financial evaluation form and provided the sin cards and our signature to authorize CIC to check our record from CRA. Not sure why they still want us to send the Option C prints. Anyone experienced the same issue?
I called CRA and was told I can simply print the Option C from my CRA online account. Just did and mailed them out to CIC.
