Conservative leadership candidate Kellie Leitch says she would move Canada’s embassy in Israel from Tel Aviv to Jerusalem if she becomes prime minister.

“In the wake of the recent UN vote and the comments of John Kerry, Canada must demonstrate its support for Israel … As Prime Minister I will move the Canadian embassy in Israel to Jerusalem,” Leitch tweeted Thursday evening.

I will move the Canadian embassy in Israel to Jerusalem. RETWEET if you agree. #cpcldr — Kellie Leitch (@KellieLeitch) December 29, 2016

Leitch’s commitment, which echoes Donald Trump’s, is a provocative one that’s been made and abandoned in the past. Jerusalem, holy land for Jews, Muslims, and Christians, is disputed territory.

Until 1967, the western half was controlled by Israel and the eastern half by Jordan. In the 1967 Six-Day War, Israel captured and annexed the eastern half, but its claim to the territory continued to be disputed by Palestinians and unrecognized by most of the rest of the world.

If the U.S. or Canada were to moved their embassy there, it would likely be viewed by the Arab world as supporting Israel’s occupation.

Leitch’s comments comes amidst the latest tensions between the Obama administration and the Israeli government. U.S. Secretary of State John Kerry strongly denounced Israeli settlement-building earlier this week, and Israeli Prime Minister Benjamin Netanyahu called Kerry’s comments “biased” and “obsessively focused” on settlements.

But Leitch’s vow to move Canada’s embassy in Israel is not a new idea. U.S. President-elect Donald Trump promised to move the U.S. embassy to Jerusalem on the campaign trail and Trump’s campaign adviser on Israel, Jason Greenblatt, told Israel’s Army radio in a post-election interview that Trump was “going to do it.”

The move was also promised by former prime minister Joe Clark in the 1979 election campaign, which he won. But just two days after being sworn in as prime minister, the pledge plunged Clark’s new government into “a diplomatic crisis”, according to CBC reporting at the time.

Clark said the move would support a peace accord that was signed between Egypt and Israel. But Egypt’s ambassador to Canada at the time, Hassan Fahmy, said the move would “put lots of obstacles and spill gas on the existing flames, which is not going to help the peace settlement in the area.”

Clark eventually backed away from the decision.
