Eastern Ontario in the context of "Upper Rideau Lake"

Brockville is a city in Eastern Ontario, Canada, in the Thousand Islands region. Although it falls within the United Counties of Leeds and Grenville, it is politically independent of the county. It is included with Leeds and Grenville for census purposes only.

Known as the "City of the 1000 Islands", Brockville is situated on the land which was previously inhabited by the St. Lawrence Iroquoians and later by the Oswegatchie people. Brockville is one of Ontario's oldest communities established by Loyalist settlers and is named after the British general Sir Isaac Brock.

Southern Ontario is a primary region of the Canadian province of Ontario. It is the most densely populated and southernmost region in Canada, with approximately 13.5 million people, approximately 36% of Canada's population of 37 million. The region lies south of the province's other primary region, Northern Ontario, although the exact northern boundary of Southern Ontario is disputed. However, its core region is situated south of Algonquin Park, the latter being in an area of transition between coniferous forest north of the French and Mattawa Rivers and southern deciduous forest. It covers between 14 and 15% of the province, depending on the inclusion of the Parry Sound and Muskoka districts which also lie in the transitional area between northern and southern forest regions. Southern Ontario differs greatly from Northern Ontario, having a much higher population density, a different climate, and a different culture than its northern counterpart. It is broken into smaller subregions, including Central Ontario, Eastern Ontario, the Golden Horseshoe, and Southwestern Ontario.

The core area of Southern Ontario is part of the Quebec City–Windsor Corridor, which extends northeast into southern Quebec. The transitional northern area of this primary region extends north to the Mattawa River and occupies part of the Grenville Geological Province of the Canadian Shield, which also extends northeast into southern Quebec; most of Northern Ontario lies within the Superior Geological Province.

The Rideau River (French: Rivière Rideau, Ojibwe: Pasapkedjinawong) is a river in Eastern Ontario, Canada. The river flows north from Upper Rideau Lake and empties into the Ottawa River at the Rideau Falls in Ottawa, Ontario. Its length is 146 kilometres (91 mi).

As explained in a writing by Samuel de Champlain in 1613, the river was given the name "Rideau" (French for 'curtain') because of the appearance of the Rideau Falls. The Anishinàbemowin name for the river is Pasapkedjinawong, 'the river that passes between the rocks'.

The Petawawa River is a river in the Saint Lawrence River drainage basin in Nipissing District and Renfrew County in eastern and northeastern Ontario, Canada. It is located in the traditional territory of the Algonquin and Anishnabek people. This territory is covered by the Upper Canadian Treaties. river flows from Algonquin Provincial Park to the Ottawa River at the town of Petawawa, and is only one of two major tributaries of the Ottawa River to flow completely freely (the other being the Dumoine River). The river's name comes from the Algonquian for "where one hears a noise like this", which refers to its many rapids.

Franco-Ontarians (French: Franco-Ontariens or Franco-Ontariennes if female, sometimes known as Ontarois and Ontaroises) are Francophone Canadians that reside in the province of Ontario. Most are French Canadians from Ontario. In 2021, according to the Government of Ontario, there were 652,540 Francophones in the province. The majority of Franco-Ontarians in the province reside in Eastern Ontario, Northeastern Ontario, Central Ontario (including the Greater Toronto Area), although small francophone communities may be found in other regions of the province.

The first francophones to settle in Ontario did so during the early 17th century, when most of it was part of the Pays d'en Haut region of New France. However, French settlement into the area remained limited until the 19th century. The late 19th century and early 20th century saw attempts by the provincial government to assimilate the Franco-Ontarian population into the anglophone majority with the introduction of regulations that promoted the use of English over French, for example Regulation 17. During the late 1960s and 1970s, because of the Quiet Revolution, Franco-Ontarians established themselves as a distinct cultural identity – having only identified as French Canadians before. Francophone rights were furthered in the 1970s as a result of C'est l'temps, a Franco-Ontarian civil disobedience movement that pressured several provincial departments to adopt bilingual policies.

Renfrew is a town on the Bonnechere River in Renfrew County, Ontario, Canada. Located one hour west of Ottawa in Eastern Ontario, Renfrew is the fourth largest town in the county after Petawawa, Pembroke and Arnprior. The town is a small transportation hub connecting Highway 60 and Highway 132 with the Trans-Canada Highway. Renfrew is also known historically for its role in the formation of the National Hockey League. It lies about 5 kilometres from the Quebec border, about 10 kilometres by road. Renfrew makes most of Canada’s hockey tape.

The United Counties of Leeds and Grenville, commonly known as Leeds and Grenville, is a county and census division in Ontario, Canada, in the Eastern Ontario subregion of Southern Ontario. It fronts on the St. Lawrence River and the international boundary between Canada and the United States, opposite of the State of New York. The county seat is Brockville. The county was formed by the union of the historical counties of Leeds and Grenville in 1850.

King's Highway 41, commonly referred to as Highway 41, is a provincially maintained highway in the Canadian province of Ontario. The 159.6-kilometre (99.2 mi) highway travels in a predominantly north–south direction across eastern Ontario, from Highway 7 in Kaladar to Highway 148 in Pembroke. The majority of this distance crosses through a rugged forested region known as Mazinaw Country. However, the route enters the agricultural Ottawa Valley near Dacre. A significant portion of Highway 41 follows the historic Addington Colonization Road, built in 1854.

Highway 41 was first assumed in 1935, though ironically the initial route is no longer part of the highway. It was extended north to meet the eastern terminus of Highway 60 at Golden Lake in 1937. The following year, a southern discontinuous section of the highway was established north from Picton in Prince Edward County. A series of changes in 1957 extended Highway 60 east to Renfrew and Highway 41 north to Pembroke; this established a concurrency of the two highways through Eganville, which remains to this day.

Lake Mazinaw is a lake in the Addington Highlands north of Kaladar in Eastern Ontario. The lake is situated on the upper Mississippi River. It has a perimeter of 49 km (30 mi) and averages 41 m (135 ft) in depth with a maximum depth of 145 m (476 ft), making it the seventh-deepest lake in Ontario, including the Great Lakes. There is a narrows which divides the lake into two sections: South Mazinaw, and North Mazinaw, with North Mazinaw being larger and deeper.

Bon Echo Provincial Park encompasses the central section of the lake, including the narrows between North and South Mazinaw and the Bon Echo Rock formation attracts rock climbers from all over the world. The lake's name comes from Mazinaabikinigan-zaaga'igan, meaning "painted-image lake" in Algonkian, referring to the pictographs on Bon Echo which overlooks the lake. Bon Echo rock, located on the eastern side of North Mazinaw, features over 260 native pictographs- often confused with petroglyphs – the largest visible collection in Canada - including the Ojibwa trickster figure and culture hero, Nanabush. The Rabbit man is the most famous pictograph visible today.
