The province announced last Wednesday that it was expanding eligibility in an effort to bolster defences against the Omicron variant of the coronavirus. Pharmacies were able to start offering the boosters to younger adults on Friday, but now Ontarians can make appointments through the province's or a local public health unit's website.

The change in booster availability comes after the province tightened up restrictions. As of Sunday, restaurants, retailers, gyms and other indoor settings in Ontario are only allowed to open at 50 per cent capacity. Indoor social gatherings are limited to a maximum of 10 people, while outdoor gatherings can only have 25.
