As per my experience you don't have to. The immigration office who makes you sign the COPR applies it on your behalf at the time of landing, although I read in the forum that you need to carry a filled form. You just need to provide her your Canadian address (which you will have it anyway ready on your Good accompanying or Goods to follow list).
I landed in Toronto with my family and the immigration officer went ahead and applied for our PR cards (as it is part of the landing procedure itself).
