"It can also be a threat in some countries Britain isn't very popular. The British embassy in Iran was attacked last year if it was a joint embassy, our Canadian diplomats would have been in danger."

Hague said the two nations have stood "shoulder to shoulder" over the past century as allies and it is only "natural" that the two countries "link up" embassies in places that suit both countries, noting it will save money and increase both countries' reach abroad.

NDP Leader Tom Mulcair slammed the idea of sharing embassies with Britain during question period, while interim Liberal leader Bob Rae said the decision "doesn't make sense."

For example, British envoys will soon get space at the Canadian embassy in Haiti and a Canadian diplomat will work out of the British offices in Burma, Baird said.

"This is a manifestation of a lack of confidence. Any mature nation wouldn't even ask the question," Mel Cappe told Power Play. "This is merely a matter of sharing facilities. I don't see this as a problem at all."

Foreign Affairs Minister John Baird defended the announcement Monday that Canada and Britain will be sharing embassies abroad, dismissing "speculation" that the move will erode Canadian sovereignty.

Others, like comedian Rick Mercer, took to Twitter to express their chagrin at the news.

Hague said the agreement between the two countries to share diplomatic resources is "about speed, flexibility and practicality."

"Hey, CPC, why stop at embassies? Who needs the National Archives? We can save money by studying British history instead," he tweeted.

"We can afford to behave like a sovereign country," he added. "We are not broke."

"It's not in any respect about two diplomats trying to work for the same country."

Addressing reporters along with British Foreign Secretary William Hague in Ottawa, Baird said the decision to share some embassies with British diplomats is simply a cost effective, practical move.

A former Canadian ambassador slammed the plan as "stupid" while Bob Rae said Canada was "receding" from the world stage under Prime Minister Stephen Harper's leadership.

"We're two separate countriesand in some instances we have competing interests," Rae told Power Play.

"This is a dumb idea. There are many parts of the world where it's best not to be identified with Britain, such as in the Caribbean and Africa where Britain was a colonial power," Louis Delvoie, a former Canadian ambassador and current diplomatic relations expert at Queen's University, said in a statement.

In a written statement provided to CTV News Sunday, Hague noted British Prime Minister David Cameron's remarks to Parliament last year, that referred to Canada and the United Kingdom as "two nations, but under one Queen and united by one set of values."

"Britain is a great countrybut they're not us. We've spend a long time trying to establish that we're an independent, sovereign country," Paul Heinbecker, former Canadian ambassador to Germany, told CTV's Power Play Monday.

"The British have baggage. They particularly have baggage in the places that we're talking about. Countries in Asia and Africa didn't enjoy their colonial period with the British."

Others, like Delvoie, disagreed.

Officials told CTV News that the two countries will also explore sharing embassies in the growing economic hot spots of Asia.

Noah Richler, son Women Canada Goose Hybridge Lite Jacket Red Ireland Sale of Canadian literary icon Mordecai Richler, also joined those speaking out against the decision to link embassies, suggesting it was a slippery slope to begin sharing typically sovereign responsibilities with a former colonial power.

"Have I had a stroke? Remember the good ol' days, five minutes ago, when we were sovereign?" Mercer wrote.

The move is also seen as an attempt to countervail the European Union's push to extend its presence abroad in the expanding European External Action Service.

Reaction came fast and furious after word of shared embassies emerged ahead of the official announcement Monday.

Heinbecker also wondered why Ottawa scheduled a news conference with Hague to announced shared embassies if the move was simply an administrative one, as Baird said.
