About this data
This page summarizes 173 incidents recorded in Cornwall, Ontario during December 2025, based on the official police / municipal open-data portal for Ontario. The figure represents the last complete calendar month with published counts, covering December 2025 only, not a year-to-date total and not the interactive map window. Records in the feed span 2025-09-11 to 2025-12-10, with December forming the headline month.
The interactive map shows a separate 60 days view with 1,310 incidents, which is larger because it covers a rolling window rather than a single calendar month. The category breakdown shown alongside reflects the broader 2025 mix, including Theft, Assault and a large Other grouping, helping readers place December 2025 in context without confusing monthly and annual figures.
Recent trend
Year-over-year change is not available for this December 2025 page. The archive year series contains only 2025, with 2,096 dated incidents recorded for that year, so there is no complete prior calendar year to form a comparison pair. The 173-incident December total therefore stands alone as a monthly count, rather than as part of an annual increase or decrease. Additional years of published Cornwall data would be needed before a December-to-December or full-year comparison could be shown on this page.
Category breakdown
The 2025 category mix behind this page is led by Other with 1,318 incidents, or 62.9%, followed by Theft with 466 incidents, or 22.2%, and Assault with 82 incidents, or 3.9%. These figures describe the broader 2025 grouping, not a breakdown of the 173 incidents in December 2025 alone. Within Other, Other crime accounts for 1,166 incidents, or 88.5% of Other and 55.6% of the total, so the top rank reflects that grouped slice rather than a single offence type. Threats and Harassment counted under Other are person offences from open data, not physical assault, which is tracked separately as Assault.
What this means
For Cornwall, December 2025 stands as a 173-incident month against a 2,096-incident 2025 file. What stands out is the pattern in two slices: Other at 1,318 incidents, or 62.9%, and Theft at 466 incidents, or 22.2%, while Assault accounts for 82 incidents, or 3.9%. Most of Other is Other crime at 1,166 incidents, or 88.5% of Other, with Threats at 64 and Harassment at 32 beside it. Readers should read December as a monthly entry within that 2025 mix, since year-over-year change is not available.
FAQ
How many incidents were recorded in Cornwall in December 2025?
Cornwall recorded 173 incidents in December 2025, the last complete calendar month with published counts. This is a calendar-month total, not the interactive map's rolling 60-day window total of 1,310 incidents. The broader 2025 archive holds 2,096 dated incidents, so the December figure should be read as one month within that larger annual set.
What was the most common type of incident in Cornwall?
In the 2025 mix, Other was the most common grouping with 1,318 incidents, or 62.9% of the 2,096 records, followed by Theft with 466 incidents. Other is not unexplained: Other crime accounts for 1,166 of those, plus Threats with 64, Harassment and Impaired & dangerous driving with 32 each, Weapons offences with 17 and Drugs with 7. Threats and harassment are person offences, not physical assault.
Has incident volume gone up or down compared with last year?
Year-over-year change is not available for this period for Cornwall. The archive currently provides a single complete-year point: 2,096 incidents in 2025. With only that year in the series, there is no prior complete year to compare against, so December 2025's 173 incidents cannot be framed as an annual rise or decline.
Which Cornwall neighbourhoods had the most incidents?
Neighbourhood-level breakdowns are not available for this Cornwall source, so we cannot rank neighbourhoods by counts. The open feed publishes city-level locations for the 2,096 incidents in 2025 without a consistent neighbourhood field to group them. Use the interactive map points around December 10, 2025 to explore locations, rather than a neighbourhood table.
Where does Cornwall's crime data come from?
Figures come from the official police / municipal open-data portal for Ontario covering Cornwall. The December 2025 headline of 173 incidents and the 2025 category mix, including 82 assaults and 105 violent-category incidents within 2,096 dated records, reflect what was published there. Coverage in this extract spans September 11, 2025 to December 10, 2025 for mapped occurrences.
How up to date is this Cornwall page?
The page headline reflects December 2025, the last complete calendar month, with the latest mapped occurrence on December 10, 2025 and earliest coverage from September 11, 2025. The interactive map separately shows a rolling 60-day window with 1,310 incidents, which differs from the monthly 173 incidents and the 2,096-record 2025 archive.
