The Maher Arar case

Could the case of Maher Arar, a Syrian-born Canadian citizen, who was deported by US authorities to Syria during a stop-over at New York's Kennedy Airport, cause an international incident between Canada and the United States? Arar claims he was tortured for ten months in his native country. Thus far Jean Chrétien, who is about to be replaced by Paul Martin as Prime Minister, has declined to convene an inquiry into the matter.
