Prime Minister Justin Trudeau says he is working towards a full investigation into the Ukrainian International Airlines flight that crashed earlier this week to get answers for Canadians.

"Iran’s admission that it unintentionally shot down Flight 752 is an important step towards providing answers for families. But a full and complete investigation must be conducted," Trudeau says.

On Jan. 10, 2020, Trudeau met with Minister of National Defence Harjit Sajjan and François-Philippe Champagne, Minister of Foreign Affairs, to discuss the investigation into the Ukranian International Airlines flight that crashed earlier this week.

Iranian President Hassan Rouhani says an investigation into the crash has determined that missiles fired due to human error caused the crash and offered his regrets regarding the "disastrous mistake."

All 176 passengers aboard the flight, including 57 Canadians and eight Winnipeggers, died in the crash.

On Saturday, Jan. 11, Trudeau posted online that he had spoken with Rouhani in a phone call where the Iranian president shared his regret for the crash.

Trudeau acknowledged the apology as an important step for Iran but also shared the emotions being experienced by many Canadians as a result of the tragedy: anger, pain, and grief. He then insisted on a full and complete investigation, which Rouhani agreed to.

Rouhani also committed to allowing international participation in the investigation, including from Canada.

Trudeau gave an update on the latest developments with Iran at the National Press Theatre in Ottawa Saturday.

In an online post Friday, Trudeau wrote about his meeting with Sajjan and Champagne regarding an investigation into the plane crash.

"Families of the victims of Flight PS752 & Canadians have questions. And they deserve answers," the prime minister says.

Trudeau says the latest information on the investigation and the current situation at the time in Iran were discussed. 

On Friday, Jan. 10, 2020, Trudeau spoke with Japanese Prime Minister Shinzo Abe, who shared heartfelt condolences to Canadians grieving the loss of loved ones due to the Ukraine International Airlines crash.

In a summary of the call between Trudeau and Abe, both leaders agreed on the necessity of a "thorough, credible, and transparent" investigation into the crash.

They also discussed working together on this issue, furthering cooperation and relations between Canada and Japan on international issues.

Trudeau will attend a vigil in Edmonton on Sunday, Jan. 12, 2020, to pay his respects to the victims of Flight 752.

The event will be hosted by the University of Alberta and the Iranian community in Edmonton.
