Despite similar economies, extreme climates and thin populations, there are startling differences in how Canada and Australia are tackling security challenges, Matthew Fisher says.

What NORAD's annual Santa videos are a chance to remember that it is Canada’s most important military alliance, Matthew Fisher says.

New NATO figures published Friday estimate Canada will spend around 1.31 per cent of its GDP on its military this year — the same as last year, and short of NATO's two per cent target.

Speaking at the Halifax International Security Forum, U.S. national security advisor Robert O'Brien likened Huawei's implementation into Canada's network as a "Trojan Horse," and called for the release of the two Canadians Michael Spavor and Michael Kovrig in China.

Prime Minister Justin Trudeau is expected to travel to London next month where recent comments by French President Emmanuel Macron questioning the viability of the alliance threaten to overshadow a celebration of NATO's 70th birthday.

It's as if the parties' thin defence platforms carry signs in invisible ink that say, 'Not to be discussed,' says Matthew Fisher.

The federal government announced last month that U.S. defence giant Lockheed Martin beat out two rivals in the long and extremely sensitive competition to design replacements for the navy's frigates and destroyers.

The federal government is giving U.S. defence giant Lockheed Martin the first crack at inking a contract to design Canada's $60-billion fleet of new warships.

Canada is expected to spend an estimated 1.23 per cent of its GDP on defence in 2018 - down from 1.36 per cent last year
