The city's COVID-19 response is getting a shot in the arm with the opening of three Toronto vaccine clinics

Mayor John Tory announced on Monday, March 8, that three "mega sites" would be opened two weeks ahead of schedule next week.

The three sites will be open to the public beginning on Wednesday, March 17, and are located across the city.

The sites are at the Metro Toronto Convention Centre, Scarborough Town Centre and Toronto Congress Centre.

Toronto says the three clinics will run seven days a week, from 11 a.m. to 8 p.m.

But city officials expect that Toronto could eventually have nine mass vaccination clinics operating for 24 hours a day — but that depends on the availability of COVID-19 vaccine doses.

As of now, appointments at the mass vaccination sites are only available for residents over the age of 80, and details on how to book a vaccination appointment will become available over the next few days, according to the city.

According to Ontario's vaccination schedule, seniors under the age of 80 and essential workers will start to be vaccinated in early April.
