I have started my returns for the year 2022, and status shows as in-progress. Am I suppose to mail the hardcopies ? or does the online submission suffice?

You can electronically file your return and it will directly send to the Canada Revenue Agency (CRA) for you. It is completely optional whether you want to mail it or submit it online. 

If you choose to submit your return electronically, after your return is Netfiled, you would see a confirmation number on your screen when done. If you have signed up to receive email from the Canada Revenue Agency (CRA), you will receive an email from them saying they will process your tax return. In order to know if it is approved or done, the CRA will send you a Notice of Assessment in your CRA My Account along with a notification to your email after they have assessed it. You should receive a Notice of Assessment (NOA) within 2 to 8 weeks.

In this CRA link, you can Get a copy of your notice of assessment.
