Tucked into the southern Alberta plains roughly 65 kilometres south of Lethbridge, Warner sits at the crossroads of Highway 4 and Highway 36, placing it in a strategically connected position within the County of Warner No. 5. The village lies about 38 kilometres north of the Montana border and Interstate 15, making it a natural stop along one of the main corridors linking Alberta to the United States. Nearby communities include the towns of Stirling and Milk River, both of which share the agricultural character that defines this corner of the province.
Warner is a farming community with a population of 364 residents, according to the 2021 Census conducted by Statistics Canada. That figure represents a modest decline of 2.4% from the 373 people recorded in the 2016 Census, which itself was a notable increase of 12.7% from the 331 residents counted in 2011. The village covers a land area of 1.16 square kilometres and had a population density of approximately 313.8 people per square kilometre in 2021. Warner is home to the Devil’s Coulee Dinosaur Heritage Museum, which features a Hadrosaur nest and embryo, ancient fossils, and dinosaur models. The village is also notable for its Warner elevator row, a collection of four historic wood-cribbed grain elevators standing alongside the Canadian Pacific Railway at the east entrance to the village. Only one other comparable elevator row survives in Canada, found in Inglis, Manitoba. Regional attractions within easy reach include the Stirling Agricultural Village, a National Historic Site of Canada, and Waterton Lakes National Park to the west.
