Hi there, @mycfreight.
When you say you can't change the language, could you specify if you're encountering any error messages or if the option is missing entirely? Any additional information would be greatly appreciated so we can assist you better based on your needs.
In Canada, QuickBooks Online (QBO) supports two languages, English and French. You can switch between these based on your preferences. Here's how to change the language in QBO:
1. Click the Gear icon in the upper-right corner.

2. Select Account and settings.
3. Navigate to Advanced, and under the Language section, click Edit.

4. Choose your preferred language, click Save, and then select Done.

Please let me know if you have any additional questions.
