You can hold a Canadian passport as a citizen (a PR cannot).
A PR must live in Canada two of out of every five years to maintain status (a citizen does not).
Citizens can vote (PRs cannot).
You must have citizenship to qualify for certain jobs (some government jobs,
police). -PRs can get police jobs.
If you are a PR and is convicted with a serious crime, you could be inadmissible and immigration can start a removal order proceedings against you.
Those r correct... Other than those there's no diff between a PR & a Citizen.
