No,法院只管上诉的，不上诉，移民局取消就取消了。请看官网关于申明放弃pr的第1个例子，里面的3个and如果你想一次达成3个目的，才需要申明放弃。For example, if you:
know you have not met your residency obligations by being outside of Canada for a long period of time, and
would like to visit Canada, and
do not want to wait for a visa officer to do a formal assessment of your permanent resident status
OR
would like to avoid processing delays at the Port of Entry
