wit PR it's only probational status before full rights as Canadian. Here are scenarios'.
with PR:
1. U can loose it if you drive and convicted of bodily harm traffic accident and serve 1 day in jail, if you are convicted of just DUI even with no one harmed it's same.
2. Combination Minor drug offenses, petty shoplifting, 1 assualt stacked up is automatic deportation, this happened to too many guys I know. Local police enforcements, IRCC & CBSA is beefing to deport these kind of PRs even they were in Canada 1 month old who came with family, couple of guys in GTA and BC with long list of petty mischiefs were deported to England & Netherlands even they were here since as child but not born here with PR.
3.PR Can lose status if you are member of street gang or hang around their clubs or crackhouses and there is bust and u lose. So watch who hang around with or clubs you drink. IRCC, Cbsa and local police enforcements also are cracking down gang bangers with PR status. Recently their is spike of deportations of hells angels, bloods, Crips, Jamaican street gangs, Italian & latin maffia with PR status have been deported, u don't have to commit a crime but just getting arrested at places and u are down the drain.
4.pr just like citizen can lose status if accused and misrepresentation but according to C6 when effective they have chance better chance than PR to proof they did not misrepresent. But PRs have to leave the country within days of conviction and IRCC who handle or PRs case like this are very consistent with rejections and 1 in 10 convicted are deported.
scenario above don't apply to Canadian citizen, u are convicted of crime you do your time.
