A walk-in vaccination clinic drew hundreds of people to the Julie McArthur Regional Rec Centre in Owen Sound Tuesday.
Public Health arranged a two-hour window where people could show up for a vaccine without making an appointment.
The line of people waiting for their shot snaked around the building and doubled back on itself before reaching the doors to the building.
By 5:30 p.m. volunteers were notifying newcomers to the massive lineup that they could wait, but they may not have enough shots left that day by the time they reached the front of the line.
Another walk-in mass vaccination clinic is set to be held this afternoon in Hanover at the P & H Centre from 4:30 to 6:30.
These clinics are for those 18 years an older and will offer Moderna vaccine, both first and second dose.
