A Toronto police officer convicted last year on charges related to the 2010 G20 Summit, will learn his punishment this week.
A sentencing hearing for Superintendent Mark Fenton is expected to last two days.
Fenton was found guilty in 2015 of discreditable conduct and ordering unlawful arrests during the event.
Officers in full riot-gear used “kettling” tactics to surround and arrest hundreds of protesters; the majority were never charged.
The prosecution is pushing for a one-year demotion.
Those caught up in the mass protests say the officer should be relieved of his duties.
The hearing comes about a week after The Ontario Court of Appeal ruled two G20 class-action lawsuits could proceed.
