I'm new in Canada and have never filed a Canadian tax return, so I do not have a CRA Account number. Can I still complete my tax return on turbotax?

Yes, you can still complete your Canadian tax return with TurboTax. You will need to print and mail out your return as this is your first return with the CRA.
