Ottawa County (Province of Canada electoral district)

Ottawa County was a historical electoral district in the Province of Canada, used for elections to the Legislative Assembly. It was located in what is now the Outaouais region of Quebec. The riding existed from 1841, following the Act of Union which merged Upper Canada and Lower Canada into the Province of Canada, until Confederation in 1867.

The boundaries of Ottawa County shifted during its existence to accommodate population changes and administrative adjustments. It generally included the territory west of Montreal along the Ottawa River, encompassing communities and rural areas.

Members of the Legislative Assembly (MLAs) representing Ottawa County were elected through a first-past-the-post system. The riding served as a political battleground where different parties and individual candidates competed for representation in the provincial legislature. The MLAs elected from Ottawa County played a role in the debates and decision-making processes of the Province of Canada government.

Following Confederation in 1867, the Province of Canada was divided into the provinces of Ontario and Quebec. Ottawa County was then reorganized and subdivided into new electoral districts within the province of Quebec, reflecting the new political landscape. The legacy of Ottawa County as an electoral district remains an important part of the political history of the region.
