Canada is bailing and closing it's embassy. A few of the reasons given: Their support for Syria, Iran's nuclear program, Iran's long time support of terrorist groups. Here's a couple of snippets...

Canada has closed its embassy in Iran and is expelling all remaining Iranian diplomats in Ottawa, Foreign Affairs Minister John Baird said Friday.

It wasn’t immediately clear why Canada was choosing now to sever diplomatic ties with the Islamic Republic. In explaining the move, Mr. Baird gave a laundry list of reasons: Iran’s current support for the regime of Syrian President Bashar al-Assad, its nuclear program, its long-time support for organizations Ottawa considers terrorist groups, its threats against Israel, its human-rights record and even the 1979 hostage-taking at the U.S. Embassy in Tehran.

OTTAWA - Foreign Affairs Minister John Baird delivered a diplomatic bolt from the blue Friday, abruptly and unexpectedly severing ties with Iran, shuttering Canada's embassy there and giving Iranian diplomats in Ottawa five days to get out of the country.

Baird rattled off a litany of long-standing grievances with Iran during a news conference in the Russian city of Vladivostok, where he and Prime Minister Stephen Harper are participating in this weekend's meeting of Asia Pacific Co-operation leaders.

"The Iranian regime has shown blatant disregard for the Vienna Convention and its guarantee of protection for diplomatic personnel," said Baird, adding that the government on Friday formally listed Iran as a state sponsor of terrorism.

"Under the circumstances, Canada can no longer maintain a diplomatic presence in Iran. Our diplomats serve Canada as civilians, and their safety is our No. 1 priority."

VLADIVOSTOK, Russia — Foreign Affairs Minister John Baird has severed Canadian ties with Iran over its sponsorship of terrorism and amid fears about the safety of diplomats in the country.

Baird says the Canadian embassy in Tehran will close immediately and Iranian diplomats in Canada have been given five days to leave.

The skeleton staff that was operating Canada's Tehran mission has already fled the country.

Baird says he's worried about the safety of diplomats in Tehran following recent attacks on the British embassy there.

"The Iranian regime has shown blatant disregard for the Vienna Convention and its guarantee of protection for diplomatic personnel," he said.
