Is there a difference between Blackboard and Canvas if my content is from Pearson?

Canvas: Content is accessed through the Flash Books link. Before the semester begins, you will receive and email about your course from Pearson about your course and how to pair your course.

Blackboard: Content is access through content paired with your course and an access code. Before the semester begins, you will receive and email about your course from Pearson about your course and how to pair your course.
