Health officials are urging people to be patient and to let those in priority groups get their swine flu shots first.
Chief medical officer of health Dr. Arlene King and Health Minister Deb Matthews made the appeal at a news conference yesterday.
It comes as clinics, mostly in southern Ontario, have been swamped this week, and two Toronto clinics had to close their lineups.
Among those reporting larger-than-expected lineups was a clinic in Owen Sound, where people started showing up at 7:30 in the morning.
King and Matthews both say there will be enough vaccine for everyone who wants it.
