Hello again soraya952,
It's great to see you're still working out the details of getting your tutoring agency set up properly in QuickBooks Online. You've got good questions and once again, I'm here to help make sure you find the answers you need.
This is another question that's perfect for an accountant or the CRA. There are a number of things that go into determining when and if sales taxes are something your business charges, so it's best to go over the details of your business with a professional so that you can be sure you have the right details moving forward. This will save you from having to make corrects or potentially deal with penalties later.
As always, the My Accountant tab in QuickBooks Online is there to help you connect with an accountant by inviting them as a user or by using the Find a pro to help button. To see if there's someone you can speak with at the CRA, I recommend visiting their website to find support options.
I hope you enjoy your week. :)
