This page focuses on the 2026 year-to-date window through July, a period in which the city recorded 469 mischief incidents among a city-wide total of 5,889 incidents. Mischief therefore accounts for 8% of all categorized incidents in Markham during this window, and it ranks fifth among the 12 categories.
These figures come from the full historical archive rather than the 60-day map window, and they reflect reported incidents, not every occurrence. The page also compares Mischief with related categories, shows the year-by-year series from 2021 through the partial 2026 year, and lists the neighbourhoods with the largest 2026 year-to-date mischief counts. Neighbourhood counts are scaled to that same 469 total, so they are consistent with the city-wide category figure above.
