The protection of wetlands through the Ontario Drainage Act has been the subject of much debate. While seen as essential for increasing production and/or productivity of agricultural areas, drainage schemes have been usually approved at the expense of wetlands. Despite the presence of a referral process in Ontario's Drainage Act that is supposed to prevent the significant loss of wetland area, incremental losses continue to occur. The referral process allows landowners, drainage engineers, Drainage Superintendents, local conservation authorities and Ontario Ministry of Natural Resource officials to participate in the decision‐making process. This research examines the recommended mitigation measures and wetland gains/losses in Zorra Township between 1978 and 1997. Data sources included drainage files, wetland evaluation files, aerial photography and interviews with government officials. The results indicate that while recommended mitigation measures of drainage schemes in the vicinity of wetlands have increased, incremental losses continue to occur. The negotiated settlements among drainage engineers and the referral agencies appear to be inadequate to maintain the spatial extent of wetlands. The regulatory approach fails to motivate changes in land‐use management practices. This supports the need to include nonregulatory incentives in the effort to protect wetlands.
