It was the Mennonites who came, unsolicited, offering their services and supplies to the residents of Barrie, absolutely free of charge. And They stayed and worked here for months as I recall, till the worst of the damage was repaired.

I don't know of any other individuals or groups who volunteered their services here, at least to that extent. And yes, to the best of my knowledge the Mennonites did all that, for a community of complete strangers, because of their religious beliefs and training.
