Well you have to do it each year. If it is still like the last time I did it, I had to send the form to CRA, wait for a letter back, and then send the letter to my payroll. By the time it was all done, it was already June. I did not have the heart to do that paperwork again the following year, and changed employers to one that offered a group RRSP that did payroll deductions for RRSPs so not needed.
Have they changed the process so that you only need to send the form to your payroll department?
