Near the Easter Seals Camp in Squamish, B.C., dozens of children from as far away as Toronto and Montreal passed the time on Monday kicking a soccer ball around a field and singing Ukrainian songs around a fire. These are some of the summer activities the camp’s staff were using to distract the young campers – a group that includes Ukrainian refugees – from the fact that they couldn’t return home.

About 150 scouts are stuck at the camp owing to the strike by flight attendants at Air Canada, which has grounded the airline’s flights and disrupted travel for an estimated 130,000 passengers a day.
