Good morning. The Air Transat pilots’ union has issued a strike notice for early Wednesday morning. More on that below, along with the return of Indigenous artifacts and a rebound in employment data. Let’s get to it.

The latest: The Montreal-based airline and the Air Line Pilots Association have failed to reach a new collective agreement in talks that began last winter. Both sides are in legal strike or lockout positions on Wednesday.

The context: The union is seeking better pay and working conditions. The previous agreement was signed in 2015. The carrier on Sunday morning called the strike notice “premature.” Air Transat said it believes an agreement is possible. Air Canada’s 5,200 pilots reached a deal with raises of 42 per cent over four years.

What’s next: Air Transat says it will begin suspending flights on Monday, with a complete shutdown by Tuesday.

Why’s that: Airlines take this step ahead of possible work stoppages to avoid stranding passengers, crew and aircraft. However, the move risks stranding passengers already at their destinations, and comes just ahead of the busy holiday travel season.

The latest: The Kremlin said on Sunday that U.S. President Donald Trump’s new national security strategy largely aligned with Russia’s own vision, the first time that Moscow has so fulsomely praised such a document from its former Cold War foe.

On the ground: Russian missile, drone and shelling attacks over the weekend killed at least four people in Ukraine, after U.S. and Ukrainian officials wrapped up a third day of talks aimed at ending the war.

What’s next: Officials said the leaders of the United Kingdom, France and Germany would participate in a meeting with Ukraine President Volodymyr Zelensky in London on Monday.

Analysis: Trump’s National Security Strategy is a dramatic rejection of the world order his predecessors created

The latest: In a lot of ways, the colourful, larger-than-life pantomime is Ming Wong’s Super Bowl. The costume designer is the mind behind the elaborate costumes in Toronto’s annual holiday theatre tradition. The Globe’s theatre reporter, Aisling Murphy, jumped into the action to see how Wong took the costumes from sketch to stage at the Elgin and Winter Garden Theatre Centre, where Robin Hood will run until Jan. 4.

What’s next: There’s plenty more theatre reading where that came from. Here’s what Elsa and Anna are up to as Frozen fever hits Canadian theatre. Read about how the National Ballet keeps its Nutcracker costumes looking fresh after 30 years. Plus, consider watching Bad Hats’ Narnia, which is described as being huge-hearted and Muppety and packs a surprising emotional wallop.
