The Ontario Federation of Agriculture (OFA) is Canada’s largest voluntary general farm organization, representing more than 36,000 family farm businesses across Ontario. These farm businesses form the backbone of our robust food system and rural communities with the potential to drive the Ontario economy forward. Ontario farmers value the MDS Formulae as a proven means of separating livestock facilities and permanent manure storages from neighbouring land uses, thereby reducing complaints from these neighbouring land uses arising from livestock/manure odours. OFA wholeheartedly supports the use of the MDS formulae and guidelines to bring about adequate separation. We welcome the opportunity to provide our comments on the current suite of revisions.
