Why were so many Canadians on the plane that crashed in Iran?

The end of winter break for schools and limited travel options between Iran and Canada contributed to the loss of Canadian lives on board a flight bound for Kyiv that crashed shortly after takeoff from Tehran, according to a spokesperson for the Iranian Canadian Congress.

All 176 people aboard Ukraine International Airlines Flight PS752 were killed early Wednesday morning, including 138 passengers travelling to Canada, many of whom werestudents, researchers or lecturers with ties to schools across the country.

"Unfortunately, because of sanctions, there are not many options available to the Iranian-Canadian community to travel to Iran, and the ones that are available are not very affordable," saidYounes Zangiabadi, research director and board member of the ICC. Sixty-three of the dead were Canadian citizens.

Canada broke off diplomatic relations with Iran in 2012. There are no direct flights between Canada and Iran, which means passengers have to use connecting flights. They would have had nochoice but to take the longer but most affordable route through Kyiv, Zangiabadi said.

"We hear that most of the people, especially the students, had gone to Iran for winter holidays and were just coming back now as school is starting," saidZangiabadi. Iranian Canadiansfrequently choose this time of year to visit relatives in Iran while children are out of school, he said.

"I personally know ninepeople who were on the flight, and they all went to Iran for holidays and they were just getting back which unfortunately never happened."

On the 2016 census,210,405 Canadians list Iran as their ethnic origin, but Zangiabadi pegs the number at closer to 300,000 now, a little less than oneper cent of the population of Canada.

"Our Iranian Canadian community have long requested the Canadian government to establish a direct flight between Canada and Iran," he said.

The ICC discussed this with federal Transportation MinisterMarc Garneau but never reached a conclusion, he said.

U.S. travel ban also limits options

Travelling via U.S. flight hubs is not an option because Iran is one of the countries subject to a travel ban issued by U.S. President Donald Trump shortly after he took office in January2017.

Although the ban faced several court challenges, it came into full effect in December 2017.

Initial reports from multiple sources and community members indicated that as many as 30 people connected to the Edmonton community died in the crash. So far, CBC News has been able to confirm 13 names from that community, as well as two with ties to Calgary.

"There's no real words for it. It's devastating. We lost about one per cent of our entire community on that flight," said Payman Parseyan, who knew many people from the city's Iranian community who perished in the crash. "Every one of our community members was touched in one way or another when that plane went down."

"Many gave up a life that they had in Iran, the people that they knew, they worked tirelessly to get to the place where they were, and to lose it like this, it's terrible."
