Can I use my CoPR copy attached in passport to enter Canada more than once?

[keepitsimple12]

I did a soft landing in Canada and they did not take my relatives address for PR. They attached a copy of CoPR to my passport and said I can use this document to enter by land. I have to go to Canada for a few days and will need to re-enter again in a months time. Can I re-use the CoPR copy in my passport more than once to re-enter Canada? ( My PR card will take about 2 months)
Any advice is appreciated.

Yes, you can keep using it at land borders, but you probably won't be able to board a plane with it.
