Canada Revenue Agency (CRA) says the 10 per cent of Canadians file their income taxes on paper and their should expect “significant delays” because of COVID-19 measures.
CRA is experiencing delays in processing paper income tax and benefit returns and requests to change returns.
So it is much better to file your 2019 taxes online by June 1, 2020 and register for direct deposit to get refunds faster and avoid interruptions to benefit and credit payments
If you already filed a 2019 paper return that has not been processed yet, you can file it again online using NETFILE certified tax software.
Submit your requests for changes electronically, using Change My Return in My Account or ReFILE. If you have already submitted a request to change your return by mail that has not been processed yet, you may be able to submit it again electronically.
