There is no consistent definition of a craft brewery or microbrewery across Canada. In fact, the various provincial governments only define categories such as small brewery, microbrewery, macro brewery and nano brewery, with each classification depending on the number of hectolitres produced and that number varies from province to province. Still, most of the craft brewers tend to be small and locally owned, often by families. Some such breweries have been sold to major corporations but they are still referred to as craft brewers by most news media; after such a change in ownership, however, they may no longer qualify as members of the Provincial craft brewers associations.
