Q about giving up Canada GC

I am planing to get Canada GC due to the uncertaincy of my US GC. Since I can come back to US after landed in Canada and waiting for US GC. There is a possibility that my US GC will be approved in 2 years and I don't need Canada GC anymore. So do I need to do something to cancel my Canada GC or it will be automatically expired if I don't go back to Canada for certain period. If I don't cancel it, will it be some problem when I enter Canada or my name will be on the black list? I believe some people here may have same issue and thanks in advance for your sharing.
