It was abolished in 1867, upon the creation of Canada and the province of Ontario. Boundaries 

Stormont electoral district was based on Stormont County, Canada West (now part of the United Counties of Stormont, Dundas and Glengarry, Ontario). It was located in the eastern part of Canada West, on the Saint Lawrence River. The Union Act, 1840 had merged the two provinces of Upper Canada and Lower Canada into the Province of Canada, with a single Parliament. The separate parliaments of Lower Canada and Upper Canada were abolished.Union Act, 1840, 3 & 4 Vict. (UK), c. 35, s. 2. The Union Act provided that the pre-existing electoral boundaries of Upper Canada would continue to be used in the new Parliament, unless altered by the Union Act itself. Stormont County had been an electoral district in the Legislative Assembly of Upper Canada, and its boundaries were not altered by the Union Act. Those boundaries had originally been set by a proclamation of the first Lieutenant Governor of Upper Canada, John Graves Simcoe, in 1792:

The boundaries had been further defined by a statute of Upper Canada in 1798:

The effect of these boundaries was to reduce the size of Stormont County, with several townships removed to form the new Russell County, Ontario. Since Stormont County was not changed by the Union Act, those boundaries continued to be used for the new electoral district.
