Where the numbers come from
Case information data sources
The Public Health Case and Contact Management Solution (CCM) is Ontario's primary disease reporting system. All of Ontario’s Public Health Units report covid 19 case and outbreak data to CCM each day.
All covid 19 case and outbreak data on this page is taken from CCM as of 1:00 p.m. the day before the “Last updated” date at the top of this page.
If there is a discrepancy between numbers reported here and those reported publicly by a Public Health Unit, it is likely because the Public Health Unit hasn’t yet updated their numbers in CCM. In that case, consider the number reported by the Public Health Unit to be the most up to date.
Outbreak setting reporting sources
We create the outbreak graphs and charts from information that facilities report to their local Public Health Unit (which enters it into a reporting tool).
“Outbreak” is defined differently depending on the facility and when the outbreak was reported. The number of outbreaks, and cases per outbreak, may change over time as Public Health Units gather information through their outbreak investigations.
