Every single one of them needs to be arrested and charged with war crimes.

Edit: the Criminal Code of Canada exempts most militaries of many charges. For example the explosives act specifically states that it does not apply to military personnel operating under military orders or action.

That should be scrapped for any IDF member. Anyone who served there should charged with the same firearms and explosives offenses that an armed robber or pipe bomber would if they were committing crimes in Canada.
