War Crimes and Crimes Against Humanity

As part of the domestic and international fight against impunity for perpetrators of war crimes, crimes against humanity or genocide, the objectives of Canada’s Crimes Against Humanity and War Crimes Program (War Crimes Program) are to deny safe haven in Canada to persons believed to have committed or been complicit in such crimes, and to seek accountability for their conduct. Delivered jointly by Immigration, Refugees and Citizenship Canada (IRCC), the Canada Border Services Agency (CBSA), the Royal Canadian Mounted Police (RCMP) and the Department of Justice (Justice Canada), the War Crimes Program takes a holistic approach, which includes three main avenues to seek accountability:

  • criminal investigations and prosecutions
  • various immigration proceedings
  • citizenship revocation

In some cases, the War Crimes Program pursues all three avenues.
