What more can Canada do to assist Ukraine as the world marks the two-year anniversary of Russia’s invasion? 'The West Block' host Mercedes Stephenson sits down with retired general Rick Hillier, the former chief of defence staff and member of the Ukrainian World Congress's Strategic Advisory Council, about Canada’s role in supporting Ukraine and the plight of Ukrainian refugees. Hillier also discusses what’s needed to improve the state of the Canadian Armed Forces. Plus, Stephenson interviews Dan Stanton, the former executive manager at the Canadian Security Intelligence Service (CSIS), about the dangers of insider threats at highly critical institutions like nuclear power plants and the Royal Canadian Mounted Police (RCMP).
