Situated roughly 35 kilometres southwest of Edmonton along Highway 39, Calmar sits within Leduc County in central Alberta. The town is part of the Leduc-Nisku Economic Development Association, an economic partnership that promotes Alberta’s International Region, taking advantage of the area’s proximity to the Edmonton International Airport. Calmar experiences a humid continental climate, consistent with much of the surrounding region.
The town traces its name back to 1900, when it was named after Kalmar, Sweden – the hometown of its first postmaster, C. J. Blomquist. According to the 2021 federal census, Calmar had a population of 2,183 residents living in 893 of its 937 total private dwellings, representing a modest decline of roughly 2% from the 2,228 residents recorded in 2016. That 2016 figure itself reflected a 13.1% increase from the 2011 population of 1,970, indicating a period of growth in the years prior. The town covers a land area of 4.67 square kilometres, yielding a population density of approximately 467.5 residents per square kilometre as of the 2021 census.
