Hi there vgarneau-v-gatel,
Making sure that your account is in the right language is important for you to maximize your use of QuickBooks Online. It's a great tool that's offered in both French and English for you to be able to manage your books in the language that best suits you. I can provide some assistance.
In order to change the language of your QuickBooks Online account, navigate to the Gear Icon, then Account and settings. Select Advanced from the options in the left column, then click on Language in order to change the language of your account. Don't forget to Save.
One thing to note would be that the language of your taxes will not be able to change as this tab is only able to display in the language that your account was set to during the tax setup.
If you have any other questions, feel free to reach out here.
