You may need to speak with your school's Online Learning / eLearning / Distance Learning department about getting logged in to their Canvas environment. Each school has a slightly different process for logging in. I can provide you with some general information, but nothing specific to the school that you attend.
Hopefully you'll be able to connect with someone at your school soon that will be able to help you get logged in. Good luck!!
