Canada is set to receive up to 249,000 doses this month and Canadian officials expect to administer them within days. Health Canada said the vaccine is for use in people 16 years of age or older, but noted Pfizer-BioNTech are running further clinical trials on children of all age groups and that could change.

Pfizer and BioNTech said it will supply a minimum of 20 million doses to Canada through 2021 and as many as 76 million.

“It is encouraging to see that our mRNA vaccine is now authorized in Canada. Following U.K. and Bahrain, it is the third country to approve use of our vaccine within a week,” said Sean Marett, BioNTech’s chief business and chief commercial officer.

Canada recently amended the contract with Pfizer so that it would deliver up to 249,000 doses this month. That will mean about 124,500 of the highest risk Canadians will get vaccinated at first as two doses are required per person a few weeks apart.

Canada has contracts with six other vaccine makers as well.

The government has said 14 distribution centers will be located in large Canadian cities initially. There will be at least one in each province and two each in Canada’s four largest provinces.

“This is phenomenal news for all Canadians as we take the next step toward ending this pandemic. As soon as vaccines arrive on Ontario soil, we will be ready to deliver and administer them,” Ontario Premier Doug Ford said in a tweet.
