Earlier quoted context omitted.
I have never heard of a food bank in Ontario offering food with passed expiration dates. I previously volunteered there and most of the food was from grocery stores/corporate donors, but not expired.
Not in Ontario, but I helped sort canned goods for a charity a few times, and they were compelled by law to be much more strict with "best by" dates and dented cans than I would be at home. I assume that approach is pretty common across North America.
The food bank I worked at had guidelines per item group. Different items had different levels of strictness, though any worker was free to throw away any item if they thought it was spoiled or too badly damaged. Dents were okay as long as it remained sealed.
My guess is the strictness of the rules is driven by availability of resources and the level of need being met by the organization.
