Hello, GST is normally collected based on the revenue from your business, and then GST return needs to be filed separately. I don't have enough information about your situation (e.g. if you are collecting GST), therefore unable to provide more info. Sharing link to understand all about GST filing, hope this is helpful.  : https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/complete-f...

You can visit the CRA website and navigate to the My Business Account login page. If you already have an account, log in using your CRA user ID and password. If this is your first time, you will need to register by clicking on the 'CRA register' button and following the instructions. This will involve entering your Business Number registered for GST/HST, which has the RT program account designation (e.g., 123456789RT0001). and other validation details.

In your My Business Account dashboard, navigate to the section pertaining to 'GST/HST' under the ‘Accounts and payments’ menu or similar links. Here you can view your GST/HST account balance, transaction details, and also access options to file returns, make payments, and view previously filed returns.
