Mnjikaning Fish Weirs National Historic Site

Located on portions of the bottom of the Narrows between Lakes Simcoe and Couchiching in Orillia, the Mnjikaning Fish Weirs contains the largest and best-preserved wooden fish weirs in eastern North America, in use from about 3300 BC until the recent past. The site was cared for and used by the Huron-Wendat in the centuries immediately before AD 1650; today, the Anishinaabeg are stewards of the site. This is a sacred place that represents an ancient and ongoing spiritual bond between the Creator and all living things. Watch the video below to learn more about the site’s original use as well as future plans for the long-term interpretation of the site. (Photo: Parks Canada)
