It was just a week before filing my income tax returns this year, I realized I have provided my mom's sin number to my employee instead of mine. I know it was such a foolish mistake to have made because of our names (my last name is my mom's first name). My eyes were on fault.
I asked my employee if he could change but his everyday answer is "I'm working on that, I have to call CRA". It's still not fixed today. Can anyone help, please?
