The Iranian military shot down a civilian jetliner earlier this year, killing 176 people including 55 Canadians and 30 permanent residents.

'I don't feel this pain is healing at all. I feel, in the last six months, it has deepened in this anger and this sadness,'

Canada's transport minister says it's been 92 days since Iran told the UN aviation council that it would give the flight data and cockpit voice recorders to Ukraine.

Canada and other countries have been waiting months for Iran to hand over the flight recorders from the plane so the data can be downloaded and analyzed.

An Iranian official promised on March 11 to transfer the flight recorders within two weeks to assist with Ukraine's investigation into the crash.

Canada met with Iranian Foreign Minister Mohammad Javad Zarif at the Munich Security Conference, and Champagne told a news conference afterward that they made it clear to Zarif what Iran must do.

The criticism comes as Iran refuses to hand over black boxes after shooting down a plane with 176 people on board, including 57 Canadians.

Champagne urged Iran to hand over the black boxes to France.

He says it's been more than 30 days since the downing of Ukraine International Airlines Flight PS752 outside Tehran and it's time to end the standoff over who will process the recorders that are expected to reveal a lot about the crash.

All 176 people aboard Ukraine International Airlines Flight 752 died when Iranian missiles shot the plane down in the early hours of Jan. 8.
