Prince William and the Duchess Catherine are to visit a charity that supports pregnant women battling addiction in Vancouver on Sunday (25.09.16).
One of the royal couple's first engagements will be a trip to Sheway, which has been looking after mothers-to-be since 1993.
The organisation's manager, Patti Zettel, says their visit to the centre will be a "wonderful closing of the loop" of the work Princess Diana, William's late mother, did when she was alive.
She said: "It shows a commitment to a particular group of marginalised individuals - women and addiction - for a quarter of a century now by the royal family."
While William and Catherine, both 34, will only stay for an hour, But Patti says it will be more than beneficial to the users of the facilities at Sheway.
According to BBC News, she said: "It's a validation that their lives and their experiences have meaning and that their stories deserve to be told."
William and Catherine will head to Canada with Prince George, three, and 16-month-old Princess Charlotte on Saturday (24.09.16) for the start of an eight-day visit.
The trip will be Charlotte's first foreign engagement and she is expected to get special treatment with officials at Government House planning to build her a lavish soft-toy nursery to play in.
What's more, Canada's Prime Minister Justin Trudeau and his wife Sophie Grégoire have also arranged a meal plan for the youngsters.
Nanny Maria Borrallo will look after the pair while their parents carry out royal engagements, but the kids are expected to attend a children's party for military families in Canada.
A Kensington Palace spokesperson recently said: "This is a great opportunity for them to introduce their children to a major realm before things like schools make it difficult later on."
