Atherley Narrows Swing Bridge

The Mnjikaning Fish Weirs are one of the oldest human developments in Canada. These fishing weirs were built by the first nations people well before recorded history, dating to around 4500 BP during the Archaic period in North America, according to carbon dating done on some of the wooden remnants. The weirs were built in the narrows between Lake Couchiching and Lake Simcoe, now known as Atherley Narrows, over which Ontario Highway 12 passes today. They were preserved by the water and layers of protective silt. The weirs were built as fences using local wood species, including eastern white cedar, sugar maple, and white birch for the stakes. The weirs were used to trap the various fish species swimming through them. The early fishermen wove brush and vegetation among the weirs to make net-like fencing where the fish were guided to be speared, netted or kept for later use, particularly for consumption during the winter. The weirs – historically called ouentaronk (Huron) and tkaronto (Mohawk) – are believed to have provided the City of Toronto with its name, following a series of copy errors. They were in use for about 5,000 years, until about the early 1700s. Samuel de Champlain recorded their existence on September 1, 1615, when he passed the weirs with the Huron en route to the battle with the Iroquois on the south east side of Lake Ontario. The Mnjikaning Fish Weirs was officially recognized as a National Historic Site of Canada on 12 June 1982. It is managed by the Rama First Nation, who created the Mnjikaning Fish Fence Circle to protect and promote the site.

The Dougall Canal is a canal in Simcoe County, Ontario, Canada. It was named in 2015 for Bruce Dougall, who undertook its construction during the 1960s. It is located in Orillia on Couchiching Point, a piece of land that separates Lake Couchiching from Lake Simcoe. The development of Couchiching Point was originally going to be a denser subdivision according to plans filed in 1890. The land remained undeveloped until Dougall began development in the 1960s, but the plans changed during development to be lower density and added the canal. The new development was known as Crescent Cove, and the canal was unnamed. The canal route generally follows the path of what was originally set aside for Cumberland Avenue. By cutting the canal, 55 lots had lake access instead of the original 25. The canal and small sections of land on either side of it were owned by the city, who had responsibility for keeping it operational. They failed to do so, and by the 2000s it was overgrown. The city agreed to give the land to the homeowners, many of whom had already build on the land. In exchange, the homeowners association took over maintenance of the canal. The canal is 12 feet (3.7 m) deep in the center, but reduces to 6 feet (1.8 m) at either end where it connects to the Trent-Severn Canal system. It is about 0.5 miles (0.80 km) long, running roughly north–south across the peninsula.

Mariposa Folk Festival is a Canadian music festival founded in 1961 in Orillia, Ontario. It was held in Orillia for three years before being banned because of disturbances by festival-goers. After being held in various places in Ontario for a few decades, it returned to Orillia in 2000. Ruth Jones, her husband Dr. Crawford Jones, brother David Major and Pete McGarvey organized the first Mariposa Folk Festival in August 1961. The inaugural event, covered by the Canadian Broadcasting Corporation, featured all Canadian performers. The festival grew in popularity, size and rowdiness until the popularity of the 1963 festival (with over 8,000 advance tickets sold), and the lack of sufficient security, led to a backlash from town locals. The city of Orillia secured a court injunction to prevent the festival from continuing in the town limits. The first festival held in the Toronto area, in 1964, was at Maple Leaf Stadium. The subsequent three festivals were held at Innis Lake in Caledon, northwest of the city. In the 1970s it was held on the Toronto Islands before shifting to Harbourfront (Toronto) and Bathurst Street and later Molson Park in Barrie. In 2000, the Mariposa Folk Festival was invited back to Orillia by city councilors Tim Lauer and Don Evans. The festival continues to be held in Orillia. As well as folk music, the festival highlights other aspects of folk culture including dance, crafts, storytelling.

Orillia () is a city in Ontario, Canada, about 30 km (18 mi) north-east of Barrie in Simcoe County. It is located at the confluence of Lake Couchiching and Lake Simcoe. Although it is geographically located within Simcoe County, the city is a single-tier municipality. It is part of the Huronia region of Central Ontario. The population in 2021 was 33,411.It was incorporated as a village in 1867, but the history of what is today the City of Orillia dates back at least several thousand years. Archaeologists have uncovered evidence of fishing by the Huron and Iroquois peoples in the area over 4,000 years ago, and of sites used by Aboriginal peoples for hundreds of years for trading, hunting, and fishing. Known as the "Sunshine City", the city's large waterfront attracts many tourists to the area every year, as do a number of annual festivals and other cultural attractions. While the area's largest employer is Casino Rama, overall economic activity in Orillia is a mixture of many different industries including manufacturing, government services, customer service and tourism. Orillia is located on the shores of two connected lakes: Lake Simcoe and Lake Couchiching. Both lakes are part of the Trent-Severn Waterway. Travel north on Lake Couchiching, then through three locks and the only marine railway (Big Chute Marine Railway) still in use in North America leads to Georgian Bay on Lake Huron. Travel south-east across Lake Simcoe, through many locks (including two of the highest hydraulic lift locks in the world, Peterborough Lift Lock and Kirkfield Lift Lock) eventually leads to Lake Ontario. From either of these Great Lakes one can connect to the St. Lawrence and thence to the Atlantic Ocean.
