Trudeau defended the deal and his government's decision to approve it.
"Permits are only approved if the exports are consistent with our foreign and defence policies, including human rights," he told the House of Commons Tuesday. "Our approach fully meets our national obligations and Canadian laws."
Trudeau has stood behind the deal in the past, saying Canada had to respect contracts signed by previous governments.
On Tuesday, Trudeau took a moment to tout changes his government is making to the arms export control regime — and to take a swipe at the government of former prime minister Stephen Harper.
"We have brought new processes of transparency and accountability to international sales because Canadians expect a higher level of accountability than the Conservatives have offered us for 10 years," he said.
