How We Get Our Data
The data on this site is, for the most part, entirely manually compiled from a huge variety of government and news media sources in near real-time as information is announced. The variety of sources is used to ensure that an accurate and complete dataset is available. For every case, a source URL is provided. For reference, a list of links to the common sources for each province is found below. Do note that data from this site is largely updated by the live press briefings, and the sources below are usually delayed.
- British Columbia
- New Brunswick
- Newfoundland and Labrador
- Nova Scotia
- Prince Edward Island

In addition to the Public Health Unit data, some information regarding testing and hospitalizations is sourced from provincial data.
Historic Regional Data
In early December 2020, we launched a new feature allowing for health-region level granularity in our reporting. While much historical data was not available for things such as testing, recoveries or hospitalizations, thanks to the work of the CCODWG we were able to backfill case and fatality data for every health region in Canada. Most regional case and fatality data prior to December 1st is sourced from the CCODWG dataset.
Since the beginning of the pandemic, we've enjoyed a collaborative relationship with the CCODWG, comparing and sharing data. Their dashboard is available here, where we provide ongoing hospitalization data.
Occasionally, news media and other sources are required for individual case data for a variety of reasons, including reference purposes. This is especially true when there are changes to reporting methods, such as when we transitioned to reporting Ontario data from Public Health Units. Some of these sources are listed below.
- CBC News
- Global News
- CTV News
- Epidemiological Data from the COVID-19 Outbreak in Canada
