Soldiers carry a coffin containing the remains of one of the eleven Ukrainian victims of the Ukraine International Airlines flight 752 plane disaster, at Boryspil International Airport, outside Kiev, Ukraine, January 19, 2020.
The report, published on Thursday, found that while the shooting down of Ukrainian International Airlines flight 752 was not premeditated, it did not absolve Iranian officials of responsibility for the incident.
"If this highly politicised and illegal behaviour by Canada became the norm, all countries, even the civil aviation industry, would be the main victims."
Ottawa has repeatedly complained that Iran's official explanation did not answer many important questions about the downing of the Ukrainian plane.
Canada does not have formal diplomatic relations with Iran, making the process lengthy and complex.
