Air Canada impasse, walkable cities, reboot summer, and more

Canadian travellers face chaos as the country’s largest carrier makes moves to suspend operations. A strike and lockout notice have the airline cancelling some flights for tomorrow and warning of much more to come.

And: It sounds like a no-brainer — where you live influences how much you move. But a new study shows just how much and why it matters. Researchers tracked thousands of people who moved between cities and found their walking habits shifted with their surroundings.
