TORONTO - All adults in Ontario can book COVID-19 booster shots next Monday if three months have passed since their second vaccine dose.

Premier Doug Ford announced the sped-up booster rollout plan today as a measure to defend against the highly contagious Omicron variant.

The province says large companies will help run workplace and community clinics and some settings like pharmacies can start offering walk-in boosters to anyone 18 and older as of Friday.

Anyone who was already eligible for boosters at a longer dose interval can move appointments up to three months since their second dose starting today.

Starting at midnight the province is also capping capacity at 50 per cent for indoor venues with capacity greater than 1,000 people, including sports facilities, theatres and concert facilities.

The province says two million rapid tests are being distributed starting today at pop-up sites in settings like libraries, malls, transit hubs and some liquor stores.
