With the allowed margin of error of 0.5 fluid ounces, a "pint" which is less than 554 ml of beer is an offence, though - to the detriment of consumers - this regulation is often violated and rarely enforced. In several provinces, draft beer can also be purchased by individuals in kegs. In Ontario, for example, The Beer Store offers 70 different brands in three keg sizes, 20 litres, 30 litres and 58.6 litres.
