• ≥20% available staffed ICU hospital beds for three consecutive days, on a 7-day rolling average; AND

• No sustained increase in the number of people in the hospital with COVID-19 for seven out of 10 days, on a 7-day average.

In order to move to Phase 4, a region must meet the following metrics:

• ≥20% available staffed ICU hospital beds for three consecutive days, on a 7-day rolling average; AND

• No sustained increase in the number of people in the hospital with COVID-19 for seven out of 10 days, on a 7-day average.
