Premise: The Agassiz Brewing Company was a Canadian brewing company, founded by former Fort Garry Brewing Company brewmaster Gary De Pape. The company was established in 1998 in Winnipeg, Manitoba and based there until 2010. It was named for the prehistoric glacial Lake Agassiz which once covered much of Manitoba. Agassiz beer was available in Manitoba, Saskatchewan, Ontario, and British Columbia.
Hypothesis: Ontario is bordered by British Columbia.
