It was uncontroversial from when the Chretien Govt back I believe in 1995 changed the rules to tighten it alot. Before then and after 1979 Boat People wave that saw Canada change its policies it was quite open and thoroughly taken advantage of by overseas criminals. To the point it became a business for some lawyers to have agreements with overseas immigration brokers to pick them up at the airport after flushing their passports down the toilet enroute.
And it hummed along nicely I agree until Trudeau played his game for a selfie with Wynne.
AFAIK it was never "reformed" since back in the boat people days. Buddies of mine were still making $$$$$ representing entire boat loads of Sri Lankans 10 years ago and Harper did dick all to "fix the loop holes" - whatever you claim the "loop holes" supposedly are. And how Trudeau taking selfies changes that - well, enlighten me as to your theory, Mr Bernie Bro???? How did that magical selfie change the same fucking system as has been in place for decades???!!!????!!!
