A former senior Canadian general says it's highly likely some Canadian military members, on exchange with the United States, would have been involved at some level in the planning and co-ordination of air strikes on Iran — something the Department of National Defence disputes.

Prime Minister Mark Carney has said he supports U.S. actions to destroy Iran's nuclear program. On Saturday, speaking in Mumbai during his four-day visit to India, he said Canada as a country is not participating militarily and that the federal government was "not party to the military buildup or planning."

His statement, however, did not specifically address the fate of exchange officers currently serving with the U.S. military.

The Department of National Defence website shows that as many as 18 military personnel with the Canadian Armed Forces (CAF) are attached to Operation Foundation, working at the U.S. Fifth Fleet headquarters in Bahrain and at the Combined Aerospace Operations Center (CAOC) at Al Udeid airbase in Qatar.
