How do I invite another teacher to my Canvas courses?
This depends on a lot on how your school is setup. Some allow teachers to manually enroll another teacher in the course by going to people and clicking on the +People button, which others may don't allow teachers to add other to their course because they have removed that permission.
I would recommend reaching out to your schools Canvas Admins or Help Desk and inquire with them on how they want you to go about adding an additional teacher to your course.
