# Ottawa County (Province of Canada electoral district)

Ottawa County was an electoral district of the Legislative Assembly of the Parliament of the Province of Canada. It was located in Canada East (now Quebec), in the Outaouais region, on the north bank of the Ottawa River. It was created in 1841 and was based on the previous electoral district of the same name for the Legislative Assembly of Lower Canada. It was represented by one member in the Legislative Assembly.
In 1853, the provincial Parliament redrew the electoral map. The boundaries for Ottawa County were altered to some extent in the new map, which came into force for the 1854 general elections.
The electoral district was abolished in 1867, upon the creation of Canada and the province of Quebec.

### 1841 to 1854

The Union Act, 1840, passed by the British Parliament, merged the two provinces of Lower Canada and Upper Canada into the Province of Canada, with a single Parliament. The separate parliaments of Lower Canada and Upper Canada were abolished.
The Ottawa County electoral district was located in the Outaouais region in the western part of Canada East (now Quebec). The Ottawa River formed the southern boundary of the electoral district, and also the boundary with Canada West.
The Union Act provided that the pre-existing electoral boundaries of Lower Canada and Upper Canada would continue to be used in the new Parliament, unless altered by the Union Act itself. The Ottawa County electoral district of Lower Canada was not altered by the Act, and therefore continued with the same boundaries which had been set by a statute of Lower Canada in 1829:
