BARRIE, ONT. -- More people in Simcoe Muskoka can sign up for a COVID-19 vaccination Tuesday.

Appointments are now available for those with at-risk conditions, including people with dementia, diabetes and sickle cell disease.

Essential workers in Group Two can also sign up for a COVID-19 vaccination. This group includes those who can't work from home, including grocery store, restaurant and transportation workers. A complete list of Group 2 eligible workers is available here.

Starting Thursday, anyone 40 or older will be able to book a shot anywhere in the province.
