I am assuming from the question that you are instructor. Depending on how things work at your institution, you will need someone to get a Consumer Key and Shared Secret from Pearson. We do that centrally for our teachers but don't know how your institution works. Pearson MyLab and Mastering is where you can request the key. Once you get the key, you can install the app from the settings link in your course and then the Apps tab. You will also need the textbook code that you got with your book. That will generate codes that you give out to your students that allow them to connect as well.
When you or your school chose Pearson's MyLab, you should have been provided with an Integration Guide for Canvas. Luckily, I tried Pearson for a couple terms before dumping it. I think this link will take you to where you can get the info you need: Training & Support for Educators | MyLab & Mastering | Pearson
Also, you might want to check out the SIS & Integrations group, for some good tips from other Pearson users. There is also a good discussion at What are your experiences with Pearson MyLab LTI? in the https://community.canvaslms.com/groups/designers group.
I hope this helps,
Thank you for the information. Why did you dump it?

I might have led the pack, but our entire 2-year professional program dumped it.
Thank you for your feed back. I appreciate it.

I've helped instructors integrate it into Canvas, some like it (math and psychology), and others not so much (health information technologies) because some students had trouble with their accounts and getting help was not easy for them. Instructor did not like it because grades did not pass back to Canvas easily. It is an okay tool, if the expense is not too great for students.
