Are you able to compare age cohorts? I think most data and most data analysis on COVID is garbage, but I would trust that you know what you are doing with figures.
If you go right to the bottom of the page with the daily updates at this link, https://covid-19.ontario.ca/data , there is a note to “Download the raw data from the Ontario Data Catalogue”. If you click on that link, it takes you to a page and if you go to that bottom of it, there are several files that can be downloaded into spreadsheets.... I see there is one there called “Case rates by vaccination status and age group”. I haven’t played with that one but I suspect it might be the one that you are wondering about.
I played with some of these files a week or so ago and they actually do work fairly well.
