FLVC has its own instance of Canvas for instructional and training purposes.  If you are invited to a course within FLVC's Canvas instance, you will not be able to access it from within your institution's Canvas instance, should your institution also use Canvas.  If your institution does utilize Canvas, you may want to access FLVC Canvas from an incognito or private browsing session to avoid potential authentication issues. 
The FLVC Canvas login screen can be accessed at the following link:  This link is for schools and institutions that use Single Sign On (SSO) authentication. Please select your school or institution from the dropdown then click the "Continue" button. You will be redirected to your institution's SSO login.
If you have a non-SSO Canvas account, please use this link to log in: This link should only be used if your institution is not listed on the above SSO link.
