To convert ml to oz in Canada, multiply the milliliter value by 0.033814. Canada officially uses the metric system (mL), but Canadian food labels display US fluid ounces alongside mL due to trade alignment with the United States. Older Canadian recipes may reference Imperial (UK) fluid ounces from the pre-metrication era.
View Canadian Conversion FormulaCanada officially adopted the metric system in 1970 under the Weights and Measures Act. Milliliters (mL) are the standard unit for liquid volume on Canadian product labels, recipes, and government documents. All food sold in Canada must show volume in mL.
However, due to proximity to the United States, many Canadians still understand fluid ounces informally. Canadian food labels show both mL and US fl oz to accommodate cross-border commerce.
Modern Canadian labels use US fluid ounces (29.5735 mL) for trade compatibility with the United States. However, older Canadian recipes (pre-1970s) may use Imperial fluid ounces (28.4131 mL) from Canada's British heritage.
When in doubt: if the recipe is from a modern Canadian cookbook or website, use the US fl oz conversion. If it's from a grandmother's recipe card or vintage cookbook, it likely uses Imperial fl oz.
Drag the slider to see common Canadian product sizes in both mL and fl oz. Canadian soda cans are 355 mL (12 fl oz).
Modern Canadian food labels use the US fluid ounce. Multiply mL by 0.033814 for US fl oz, or by 0.035195 for Imperial fl oz (vintage recipes).

Modern Canada uses US fluid ounces on food labels for trade compatibility with the US. However, Canada's official measurement system is metric (mL). Older Canadian recipes from before the 1970s metrication may use Imperial fl oz from Canada's British heritage.
Canadian food labeling regulations require metric measurements (mL), but many products also show US fl oz because the same packaging is used across Canada and the US. This dual labeling makes products easier to sell in both countries.
Canada uses the metric cup = 250 mL (8.4535 fl oz). This is different from the US cup (236.588 mL / 8 fl oz) and the old Imperial Canadian cup (284.131 mL / 10 fl oz). Modern Canadian recipes use the 250 mL metric cup.
Canada began metrication in 1970 with the Weights and Measures Act and the Metric Commission. By the mid-1980s, most consumer products, road signs, and official documents used metric units. However, informal use of Imperial measures (cups, ounces) persists in daily life.
A standard Canadian beer bottle is 341 mL (11.5 fl oz), which is the traditional "Canadian stubby" size. Canadian beer cans are typically 355 mL (12 fl oz), matching the US standard can size.
