Liability issues around community sustainable agriculture

I am trying to cover all bases as I prepare a proposal for a crowdsourcing/crowdfunding approach to land rehabilitation at a synagogue and community center in Thornhill, Ontario Canada

Have any of you come across any insurance liability issues/objections to the creation of a food growing garden?

Have you seen any liability differences

If the garden is
– on public property (behind a firehouse) or private property (synagogue, church, community land)?
– fenced or unfenced

If someone encounters a health problem due to consumption of the food grown at a community garden (food safety liability)
– food is sold to an individual
– food is sold to a participant in a CSA buying group
– food is donated to an organization, which in turn prepares food, and sells the finished product.
.
My thanks to you all for any feedback you or your extended networks can provide
