Hi @CynthiaIrvine,
As referenced by @Gabriel33, if Zoom has been integrated by the Canvas team at your school it will appear in each Canvas course on the left-side in the course navigation area.
If they have completed the integration and if Zoom is not visible there, it might be hidden and you would need to follow the guidance in the How do I manage Course Navigation links? - Instructure Community - 1020 support article.
If Zoom is there, you can follow the instrutions put together by MIT in their How to Schedule Zoom Meetings in Your Canvas Course - MIT Sloan Teaching & Learning Technologies support article.
Please let us know if you need anything else.
