I don't have much knowledge about gun laws of Canada. Here is an incident from US during infamous LA riots were Koreans defended their business and properties from rioters.
I believe the government should train some volunteer civilians in Canada for the safety of their people, temples and businesses with Sticks, knives and Guns if its use is required. Ordinary Indians should learn the art called FIGHTING.
