To add the Zoom tab to your Canvas course(s) navigation, go to your specific course in Canvas, click on the Settings in the left column for your course, then click on the Navigation tab, and drag the Zoom widget up to wherever you'd like it to show up in your course navigation bar. Then click the Save button at the bottom of the window and make sure it now shows up in the course navigation bar. Here is a video tutorial of the steps:

Zoom should now be integrated into your Canvas course.
If you've added the Zoom tab to your Canvas course by following the directions above but you're getting error messages about your TOCC Zoom account when you click on the Zoom tab, you may need the TOCC IT team to add you to their Zoom account using your @tocc.edu email address. This only needs to happen the very first time you're requesting a Zoom account with TOCC. When your @tocc.edu account has been added to the list of authorized Zoom users, you will receive an email with subject, "Zoom account invitation." (Sometimes it ends up in your Spam folder!) Click the "Approve the Request" button or the link included in the email to proceed. (You can safely ignore any resulting messages warning about how your Zoom account might end up with less features, etc.)
