Good morning! This is Hanna Lee.

Today, we'll learn about the story of James Mast, a Sixties Scoop survivor who's being held in a U.S. jail. Then, what happened to the promised foreign agency registry, and more on Trump's promised Golden Dome.

Canada Post union calls for overtime ban as company, workers fail to reach agreement

The union representing about 55,000 Canada Post employees has called for a countrywide halt to overtime work, saying its negotiators will continue to review the latest contract offers from the mail carrier.

The Canadian Union of Postal Workers (CUPW) said late Thursday that members were being told to refuse any work beyond eight hours in a day and 40 hours in a week.

Canada Post issued its own statement this morning in response to the overtime ban, saying there are no rotating strikes or national work stoppages as of now, and postal operations will continue. However, the Crown corporation warned of possible delays.

The latest salvo in the long-running labour dispute came with CUPW in a legal strike position as of midnight. 

It also comes after an evening meeting between the two sides failed to lead to a deal.

Sixties Scoop survivor held in U.S. jail after attempted return to adoptive family

James Mast, 60, says he was heading to Oklahoma to care for his ailing adoptive father when tribal police on the U.S. side of the Akwesasne reservation arrested him and turned him over to U.S. Border Patrol.

What's happening: Mast, who is a Cree Sixties Scoop survivor, had no identification on him at the time, and he's so far spent six weeks in custody while U.S. authorities determine whether to deport him to Canada. He was raised in the States, he says. Though he was initially charged with unlawful "re-entry by a deported alien," the charge was dropped because of his Cree identity.

More on his background: Mast was born James Cardinal in 1964 to a family in Alberta. When he was two, his mother fell ill and moved in with his sister, who called child welfare services. He was eventually adopted by a couple who took him to Spencer, Okla. Around the mid-1990s, he was convicted of assaulting a police officer and served 17 years in prison. In 2010, he was deported to Calgary; his adoptive parents never made him a U.S. citizen, and he says he didn't know how to fight the action.

Trump's 'Golden Dome' raises major questions: Can it be built? Should it? What's Canada's role?

You may have heard by now of U.S. President Donald Trump's proposed "Golden Dome" missile defence system, modelled after Israel's Iron Dome, and that Canada has expressed interest in joining it. But how much would it cost? And is it even possible?

What it is: Trump and other U.S. officials say the system would block missiles fired from other countries and from space. That would mean it'd have to weave together existing technologies with future tech that still needs to be developed. Some say it'd also result in more weapons in space, opening up the possibility of space-based arms races.

Is it feasible?: That's unclear. Experts question Trump's three-year construction timeline and $175-billion US price tag. The Congressional Budget Office estimates it'd actually be hundreds of billions more than that and would take 20 years. Even setting aside the need for technologies that have yet to be developed, the system would require approvals over multiple presidential terms and to maintain momentum for an extended period of time.

In case you missed it

• The Trump administration has revoked Harvard University's ability to enrol international students and is forcing current students to transfer to other schools or lose their legal status. It comes after the school refused to provide information about some foreign student visa holders who attend.
   
• A neighbour has handed over trail camera footage to the RCMP at their request spanning five days before Lilly and Jack Sullivan of Pictou County, N.S., were reported missing.
   
• There's a sense of unity, said Finance Minister François-Philippe Champagne, after emerging from a summit with his counterparts across the G7.


• The new U.S. ambassador to Canada says he knows bringing in King Charles for the upcoming throne speech is meant to be a message to Trump — but there are easier ways of doing that, he says.

Shai Gilgeous-Alexander, 26, was named the NBA's most valuable player on Wednesday night, the second Canadian to receive the honour. He also grew up in Hamilton.

His father, Vaughan Alexander, spoke to CBC News about how it felt to see his son get the award. It's "100 per cent surreal," he said.

"I can't say that I knew this was going to happen or this is what we [had] written."
