Definitely agree with it. My wife left Canada 10 years ago, even claimed herself as non tax resident when she left. In order to satisfy the resettlement plan, she temporarily visited Canada twice in 6 months to open bank account, scouting schools for our children (3 yrs old and 5 yrs old), registered herself for some online course, communicate with her friends in Canada to let them know that we are about to move back to Canada, and communicate with realtors via email for housing and etc. And CIC approved her as my sponsor, and I has landed in Canada recently. In that two short visits, my wife took one of our children with her and left another one with me. It's hard, but definitely it can be arranged.
Also, all the evidences regarding the resettlement is about the Sponsor, not the PA. The sponsor needs to show the intention and the efforts to CIC that once the PA's PR is approved, the sponsor will resettle in Canada permanently. So, it doesn't matter how hard that you as a PA to work on moving to Canada, it doesn't count, it has to be the efforts made by the Sponsor.
