London sits downwind of Lake Huron often enough to earn a high snow-tolerance profile: the same centimetres add fewer points than they would in Windsor or Vancouver. That is an editorial judgement about climate, not a claim that the Thames Valley board has published a centimetre threshold.

Thames Valley District School Board's office is in London, and the board directs families to Southwestern Ontario Student Transportation Services at mybigyellowbus.ca for delays and cancellations. The preloaded setting is suburban because so many runs leave the core. Downtown walkers can switch it to urban.

Questions parents ask

Does a London closure cover St. Thomas or Woodstock?

Do not assume it. Confirm the school on the board's own finder. This page only promises a forecast for London and a link to the Thames Valley board.

Why is the snow tolerance higher than Toronto's?

Lake-effect communities are scored as more accustomed to heavy snow. Ice is not discounted. A freezing-rain morning can still outrank a routine snowfall.
