Good morning. Gander marks 25 years since 9/11 and the friendships forged in its aftermath. More on that below, along with Canada and Ukraine’s new 100-year partnership and Céline Dion’s return to the stage in Paris.

Twenty-five years after the Sept. 11 terrorist attacks, thousands are expected in Gander, Nfld., to commemorate the victims and remember the extraordinary welcome the town gave to more than 6,600 stranded passengers and crew. When U.S. airspace closed in 2001, 38 passenger planes were diverted to the small Newfoundland community.

The reunion: Many of the travellers have returned to reconnect with the residents who housed and fed them. Also there is retired air-traffic controller Patrick Woodford and former American Airlines captain Beverley Bass, whose flight he helped guide into Gander that day. Their chance encounter became a life-long friendship.

The legacy: Gander’s response became an enduring symbol of generosity in the aftermath of the attacks, inspiring the musical Come From Away and forging relationships, which have lasted for decades, between residents and the ones they called their “plane people.”

The ceremony: Governor-General Louise Arbour, former prime minister Jean Chrétien and U.S. ambassador to Canada Pete Hoekstra are among those scheduled to speak at an anniversary commemoration today.

Canada and Ukraine have signed a 100-year partnership covering defence, energy, technology and trade, as Prime Minister Mark Carney and Ukrainian President Volodymyr Zelensky met in Calgary.

The details: Canada plans to deepen joint defence production, send one-third of drones purchased through its new national marketplace to Ukraine, deliver $350-million in air-defence equipment and provide more than $430-million in loan guarantees to help Ukraine secure gas for winter.

Higher income families are increasingly more likely to have children than lower-income families, according to new Statistics Canada data suggesting that the cost of parenthood is shaping who can afford to start a family.

By the numbers: In 2023, women aged 22 to 39 in the highest-income families were about 2.5 times more likely to have a child than those in the lowest-income families - 14.1 per cent compared with 5.6 per cent. The gap has widened since 2017, when the highest-income group was 2.1 times more likely to have a child.

Céline Dion is drawing crowds across Paris ahead of her long-awaited return to the stage. Hundreds of fans have been gathering every day outside her hotel, where the Canadian star has stopped to chat, sing, dance and take selfies ahead of a month-long residency that begins Saturday.

The excitement: Nearly 500,000 tickets for the first leg sold out in less than an hour, while Paris is getting in on the celebration with mass karaoke events and a Céline pop-up shop. Train bookings to the French capital have also surged as fans arrive from across Europe.
