The CIHI data is presented in aggregate, making it impossible to know where the worst outbreaks were, which provinces had higher infection rates, or if there were larger clusters in a particular hospital. And of the data that is public, it’s fraught. For example, data from Ottawa’s public health unit is posted cumulatively, and it’s possible to verify the death rate at each institution. For Toronto, however, outbreaks and deaths appeared and disappeared from the outbreak list. The way Toronto posted this information, it was possible to miss a new outbreak within the same hospital, or to double-count.
