Waterloo Brewing traces its roots back to 1984, when it was founded as Brick Brewing Co. in Waterloo, Ontario — making it Ontario's original craft brewery. Born during the early microbrew movement in Canada, the company built its reputation on locally crafted beers at a time when independent brewing was still a novelty. Over the decades it grew into what it claimed to be the largest Canadian-owned brewery, before Carlsberg completed its acquisition of the company, integrating it into its international portfolio. The brewery's portfolio spans a range of styles, from lagers to craft ales, with a strong focus on accessible, quality-driven beers for the Ontario market. Waterloo Dark holds the distinction of being the longest continuously brewed beer in the brand's portfolio, a testament to the brewery's enduring craft heritage. The lineup also includes ready-to-drink (RTD) options and mix packs, reflecting a modern approach to meeting consumer demand. In 2019, Waterloo Brewing celebrated its 35th anniversary with a special craft lager, underscoring its commitment to offering craft beer quality at an approachable price point. The Waterloo Brewing name itself was adopted to honour the company's deep roots in the Waterloo region, connecting the brand firmly to its local identity and Ontario's craft beer history.
