Data note: Monthly history starts in August 2026: Markham police calls before August 1, 2026 were recorded less completely by the source feed, so earlier months aren't compared with later ones.

Time of day
Time-of-day data isn't available for Markham. York Regional Police publishes generalized (date-level) timestamps rather than precise event times, so hourly and weekday-vs-weekend patterns can't be computed. Counts, categories, locations, and monthly history are unaffected.
