The first vaccines arrived in Ontario pharmacies this week and people formed huge lines to get the shot.

Vaccines rolled out in 160 Loblaw-owned pharmacies including Shoppers Drug Mart and pharmacies in Loblaws, Real Canadian Superstore, No Frills, Fortinos, and Zehrs locations in Ontario, the Loblaws Companies announced on Wednesday.

Pharmacies in Toronto, Windsor-Essex and Kingston area started administering the Oxford-AstraZeneca vaccine to residents over ages 60-64 as part of a provincial pilot.

Word travelled quickly and people flocked to the stores in Toronto for a chance at a shot.

The locations are listed on the Shoppers Drug Mart website and there is also information on how to book an appointment, which is recommended for most locations.

But some people had trouble getting through to make an appointment.

"I've tried to book an appointment since this morning," one person wrote. "Tried around 10 different locations. It doesn't even go to their automated system!"

While some pharmacies have reportedly also run out of the vaccine, it is still hoped that offering the shots at pharmacies will get people vaccinated quicker.

"Across Canada, there are more than 10,000 pharmacies, in rural areas and urban centres," said Jeff Leger, President of Shoppers Drug Mart. "Based on the most recent flu season, it is expected that community pharmacies could vaccinate up to 3 million Canadians each week."
