There can be delay or may be not because most of us don't know the internal process of IRCC. Assuming they must have online system where they can access online information about your finance from CRA. There should not be big delay at least. For your peace of mind you can provide SIN Number and NOA both.Out of curiosity, do you think there will be some delay (given there need for interagency coordination) for people who have provided SIN as opposed to people who have provided NOA's or NOA's / SIN both ?
