TORONTO -- A pilot project offering COVID-19 vaccines in pharmacies is expanding more broadly today.

Some pharmacies in Toronto, Windsor and Kingston health units have already started offering Oxford-AstraZeneca vaccines to residents between the ages of 60 to 64.

Justin Bates of the Ontario Pharmacists' Association says additional shots were to arrive yesterday.

That means vaccinations are set to begin at more sites today.

He says interest in the pilot has been overwhelming.

Individual pharmacies are using their own booking systems and Bates says people should check online before calling due to high call volumes.
