Ottawa keeps two clocks.
In Ottawa, as Ethernet cables snake around Parliament Hill, the capital hums with a quiet efficiency shaped by its place on the eastern edge of Canada’s business corridor. As dusk arrives noticeably in the afternoon during standard time, locals pace their schedules to maximize daylight, and coordinating with colleagues just an hour west means remembering Toronto’s clock runs slightly ahead.
