Snow day forecast for York Region District School Board

York Region District School Board serves Markham and the surrounding area in Ontario, covering 216 schools. When winter weather threatens, the closure decision is made district-wide — which is why the forecast above is centred on the district itself rather than any single campus.

Ontario averages about 150 cm of snow per year. Ontario school boards make independent closure decisions. Northern boards have higher thresholds than southern Ontario. Toronto rarely closes, while Ottawa, Sudbury, and Thunder Bay close more frequently for heavy snow and extreme cold.

How the York Region District School Board prediction works

We pull the live forecast for the district's own coordinates and score the factors that drive a closure call: snowfall accumulation and its timing relative to the morning bus run, ice and freezing rain, wind chill, and forecast confidence. The result is a probability for a full closure, a two-hour delay, and an early dismissal.

Districts announce closures between roughly 5 AM and 6 AM, working from conditions on the ground rather than the previous evening's forecast. Weather models are most reliable inside 24 hours, so checking after 6 PM the night before gives you the most accurate read.

This is an independent prediction, not an announcement. Always confirm a closure with York Region District School Board directly before acting on it.
