I became a PR in September 2021 and while filing tax it seems i need to specify the amount of money I made before become a resident? Is there an easy way to calculate this or is it all manual? Before becoming a PR I was on a work permit for a number of years and have been paying tax as normal. My T4 from my employer has my new SIN. Do i simply do some calculations as to how much I made during the year? I feel like it would be innacurate/guessing in that case..
