The human rights group said Bush violated international law when his administration utilized enhanced interrogation techniques in the questioning of enemy combatants. Amnesty also asserts Bush should be brought on charges of war crimes and torture.
"It is incumbent upon Canadian officials to investigate, arrest and prosecute former president Bush for torture when he arrives in Canada a week tomorrow," said Alex Neve, Amnesty Canada's secretary general.
Neve even went so far as to say the Mounties should be sent for Bush as soon as he sets foot on Canadian soil.
CBC News adds:
Neve said many will argue that arresting Bush is unrealistic because the United States is a close and powerful ally or that the crisis after 9-11 required extraordinary measures.
"None of those arguments justify inaction under international law," he said.
Neve conceded that arresting a former president would likely cause tension with the United States, but "taking a principled step merits that sort of strain."
Neve said the international arm of Amnesty sent a lengthy brief to Justice Minister Rob Nicholson outlining the government's responsibilities under international law and urging him to act.
"This is something the entire global movement stands behind," Neve said.
Nicholson's office did not respond to Neve's request, however.
Bush and former president Bill Clinton are slated to attend an economic conference in British Columbia next week.
