I can't comment on the rate of recidivism in Quebec, but I do have some statistics in front of me on the proportion sentenced to custody in Quebec and all provinces. In 1999-2000 the proportion sentenced to custody for guilty cases in Quebec was 23%. The national total was 28%. In 2008-09 in Quebec it was 12%, and the national proportion was 15%.
On March 9th, 2011. See this statement in context.
