Aldersyde is a hamlet in Alberta, Canada within the Foothills County. Located between Highway 2 and Highway 2A south of Highway 7, the hamlet is approximately 8km (05miles) southeast of Okotoks, 10km (10miles) north of High River and 25km (16miles) south of Calgary. The Canadian Pacific Kansas City Aldersyde subdivision runs through the hamlet.
The name "Aldersyde" was coined by a first settler for its Scottish sound, although apparently there is no place in Scotland with the same name.[2]
The population of Aldersyde according to the 2003 municipal census conducted by Foothills County is 64.[1]
