How early could Nova Scotia get to Phase 4?

The below graphic charts the earliest and latest dates we could potentially start each phase of Nova Scotia's reopening plan.
Phase 5, the final phase, is excluded since there is no time component associated with it and it will only be triggered once 75% of the population is fully vaccinated with two doses.

*The province uses 2-4 weeks as guides for each phase; this could change depending on key health indicators such as epidemiology, vaccination rates, hospitalizations, transmission and other factors.
