As food banks struggle to cope with rising demand, they – and politicians – could learn valuable lessons from volunteers in Canada about the precarious nature of charity food provision.

Curiously, this rather wonderful protest song (above) is not sung by impatient young Marxists, but wise old mainstays of the community in Sudbury, Ontario. The “big society”, if you like. For years they have been volunteers at the local food banks. And they’ve had enough.

In fact, though they express themselves politely, they are furious. Alf Judd, the director of operations at Georgina Community Food Pantry, explained their frustration:

“I began volunteering with the food bank in 1990 thinking I would do this for a couple of years; here I am 22 years later.”
