A table with three columns: "Province", "First vaccination clinic", and "Per cent jail population vaccinated." Yukon, Saskatchewan and Prince Edward Island are the three regions at the top of the table, with vaccinated percentages at 86 per cent, 73 per cent, and 72 per cent respectively.
*To obtain Ontario's vaccination figures, CBC News reached out directly to the 20 public health units with jails in their jurisdiction. Vaccination rates based on total number of vaccinated incarcerated people as provided by provincial and territorial correctional departments in May-June, 2021.

**These provinces and territories refused to disclose or told CBC News they couldn't provide their number of vaccinated prisoners (first dose) and/or a snapshot of their total jail population in May-June 2021.

***Due to this high turnover in provincial jails, both the infection and vaccination rates in this table represent a snapshot in time of affected individuals in each province/territory on one day in May-June 2021.
