Paramedics say 26 seniors arrived in hospital after a bus crash in Denbigh, east of Bancroft.
It happened on Highway 28 just before 10 a.m. Friday.
47 people were on the bus, including the driver, when it rolled into a ditch.
The seniors - members of the Algonquin Shrine Club - were on their way to Montreal to deliver toys and a cheque to a childrens' hospital.
None of the injuries are considered to be serious.
