I think Canada has a huge role to play in the idea of universal jurisdiction with regard to war crimes, crimes against humanity, and potentially crimes of genocide by documenting crimes and being an acting partner within the International Criminal Court.
As I mentioned, if Armenia finally ratified their own statute, there will be room under the ICC to bring forward a case for Nagomo-Karabakh to the ICC with a referral from Canada. I think Canada has many roles that can be played at several levels.
I can add also that if any individual responsible for this potential ethnic cleansing travelled to Canada, there could be also prosecution for crimes against humanity within Canada.
