From the Ontario CSA Directory: 'What are CSA farms? CSA farmers receive a set fee (from you - the consumer) prior to the start of the growing season. In return, you receive shares (produce) in the farm's bounty and you also share the risks due to weather and other factors beyond the control of the farmer.' You can go to the Ontario CSA Farms website for more information and to research CSA farms. On our website add 'CSA' as a keyword when searching.
