According to the government of Canada ,
If you’re a Canadian citizen living outside Canada, you must show that you plan to live in Canada when the persons you want to sponsor become permanent residents.
However, on the form IMM 1344, the sponsor is only asked which province they intend to live in with the sponsored person(s).
On form IMM 5532, the sponsor is asked when they left Canada, when they intend to return to Canada, and where they intend to live when they return to Canada.
Neither form explains how the sponsor is expected to "show" that they plan to live in Canada. What kind of evidence does IRCC expect?
