The accused pleaded guilty to two counts of mischief over $5,000 committed during the G20 summit in Toronto in June 2010.
The Crown sought a jail sentence of six to nine months followed by probation, emphasizing the need for denunciation and general deterrence.
The defence sought a conditional sentence of 12 to 15 months with house arrest.
The court imposed a 12-month conditional sentence of imprisonment (6 months on each count, consecutive) followed by 18 months of probation, balancing the objectives of denunciation and deterrence with the offender's status as a youthful first offender and his demonstrated rehabilitation efforts.
