I have a friend, she did fake marriage to a Canadian. It took her $65k, inland. They sent the application in December 2021, received request for medical exam in the end of January, she passed the medical exam in the 2nd week of Feb 2022, COPR in the end of March 2022. So it's totally about 3.5 months.
I'm very frustrated. When I had real qualification from a public college in Canada, real job at CRA (more than 1.5yrs), real marriage to a Canadian and still haven't had PR yet. (Applied in January 2022, inland, paper).
