Globe and Mail- Thousands of foreigners’ criminal convictions forgiven by Ottawa over 11-year span, raising transparency concerns
Foreigners are, in general, inadmissible to Canada if they have been convicted of an act that is considered a criminal offence in this country. But Immigration, Refugees and Citizenship Canada (IRCC) has the power to grant an exception if five years have elapsed since a person was convicted or finished a sentence.
IRCC has not, however, released a breakdown of the kind of criminal offences that were forgiven. It said in a statement to The Globe and Mail that the Immigration Minister would be involved in decisions relating to the most serious offences.

Phase 3 of Cloward Piven Strategy – create chaos by creating strife between groups. What better way to create strife than to treat foreigners better than the citizens? And letting criminals back out to re-offend raises crime statistics without offering any reason for doing so – more strife.
Remember the goal.
I wonder what the bribe was to get a pardon?
