Update:
Just received my card today.
Coincidently, my friend also get her card today, her DM & Card Mail date is also 23-MAR, imo, this means the DM & Card Mail date is real.
BY LAW you are ENTITLED to receive your new PR card, as long as you have been in Canada 730 days or more out of past 5 years. There is no such a thing as "too close to 730" or "I will deny this guy who has less than 800 days in Canada, because I am a Grand Poohbah of immigration laws and I just want so!". No such
arbitrary idiocy is written into law by the Parliament. Needles to say, some CBSA officers act as vigilantes and make up their own rules, in defiance of the law passed by Parliament, and they give hard time to people whom they assume to be most vulnerable and least able to advocate for their rights. They are scumbags, criminals who use their badge to commit crimes with impudence.
If all CBSA was doing was getting busy stopping violent, criminal illegal aliens, human traffickers and drug dealers, we could say "Ok, these guys are protecting us", and we would support it. Because no Canadian PR in his right mind wants his daughter and wife to walk the streets where they can be attacked, robbed, killed or kidnapped for servitude and slavery. But instead of doing what they have sworn to do (uphold the law and protect innocent civilians), some of them resort to sadistic actions that cause so much pain and despair to people whose only fault is being lawfully present in Canada and asking for the document that allows them to leave the country and return without hurdles.
