Co-op work permit allows you to do a full time internship that is credited and mandatory to validate your program.
It doesn't allow you to work more than 20hours while studying full time and it does not allow you to work off campus when you are done with your studies even if it is still valid and it is absolutely related to the terms on your study permit because you got it issued based on your study permit.
You will also need the co-op work permit to do an internship during the summer in order to prevent issues in your PGWP application, because many people thought that doing an internship that is credited during summer semester does not require Co-op work permit.
If, on the other hand, the internship you plan to do in not credited, you do not require co-op work permit for it.
To sum up, no you can not work more than 20hrs/week. Also when you return home, you will find on your work permit this condition : May accept employment on or off campus .... if meeting the criteria as per R186(F), (V) OR (W), which says
