On packages meant for consumers, the net quantity must be declared on the principal display panel. It must be in metric units and be in both English and French.

The net quantity must be indicated [4, CPLA 21, CPLR and 27 CPLR]:

  • by volume for liquids: in millilitres (or for amounts over 1000 milliliters, in litres)
  • by weight for solids: in grams (for amounts over 1000 grams, in kilograms)
  • by count for certain foods, such as candied apples

For catch weight products or products packaged from bulk at retail, that are less than 1000 grams (i.e., 1 kg), the net quantity may be expressed as a decimal fraction of a kilogram [27.1, CPLR].

  • For example, the net quantity of a prepackaged raw small whole chicken is 980 grams. It is acceptable to declare the net quantity for this product as "0.980 kg".

A single space should be used to separate the number from the unit of measure. For example, 500 g is acceptable where as "500g", "500   g", and "500g" are unacceptable.

Phrases such as "net", "net weight", "net contents" or "net quantity" are voluntary and not required as part of the net quantity declaration.

When the quantity is less than one, the numerical portion may be shown in either the decimal system with the figure zero preceding the decimal point (e.g., 0.5 kilogram), or in words (e.g., one-half kilogram) [26, CPLR]. Numerical fractions (e.g., 1/8, 1/4, 1/3, 1/2, 3/4, 7/8, etc.) are not acceptable in the metric system and must never be used to express metric measure.


The net quantity must be rounded to three figures, unless the net quantity is below 100. If the net quantity is below 100, it may be rounded to two figures. In addition, any final zero appearing to the right of the decimal point need not be shown. [25, CPLR].

For example: 453.59 becomes 454; 85.6 becomes 86; 6.43 becomes 6.4.

If the net quantity is exactly 500 grams or 500 millilitres, it may be expressed as [27, CPLR]:

  • 0.5 kilograms/0.5 litres (or with the appropriate metric symbol for the units)
  • one-half kg/one-half L, , or l (un demi kg/un demi L, , or l)
  • one-half kilogram/one-half litre (un demi kilogramme/un demi litre)
  • 500 g /500 mL, mℓ, ml

Language and Symbols

Net quantity declarations are mandatory information and, therefore, must be bilingual [6(2), CPLR]. The following metric symbols are considered to be bilingual (English and French). They should not be followed by any punctuation.

g: for grams
kg: for kilograms
ml, mL or mℓ: for millilitres
l, L or : for litre

The above symbols are case sensitive and only litre and millilitre measurements have case or font options. The "g" for grams cannot be replaced by "G".

When words rather than symbols are used as net quantity declarations, they must appear in both official languages. For example, the English word "gram" in the declaration "50 grams" must appear as "gramme" in the French net quantity declaration "50 grammes".

The following table shows the correct spelling of metric units of measurement in English and French when words are used instead of symbols.

Spelling of metric units of Measurement
English French
gram gramme
Kilogram kilogramme
Litre litre
Millilitre millilitre

In the French language the decimal point is written as a comma rather than a period. This is acceptable.

Legibility and Location

Foods Sold at Retail

The declaration of net quantity on the labels of prepackaged products for retail sale must appear on the Principal Display Panel (definition) [12(a), CPLR].

A minimum type height of 1.6 mm, based on the lowercase letter "o", is required for all information in the net quantity declaration, except for the numbers which are to be shown in bold face type and in the size shown in the table below. These also apply when the numerical portion is written in words (e.g., "one-half" litre). [14(2) and 14(4) of the CPLR].

Minimum Type Height for Net Quantity Declaration
Area of Principal Display Surface Minimum Type Height of Numerals
square centimetres square inches millimetres Inches
< 32 < 5 1.6 1/16
> 32 to < 258 > 5 to< 40 3.2

> 645 to < 2580 > 100 to < 400 9.5
> 2580 > 400 12.7 ½

Non-Retail Foods

There are specific requirements for net quantity declaration on prepackaged food products that have not been packaged for retail sale, such as shipping containers and foods for institutional use. For more information on these requirements refer to Measurement Canada.

When to Use Weight, Volume or Count


Section 22(1) CPLR lists the prepackaged products that are required to show their net quantity by weight. Examples include honey, cottage cheese and yogurt. Some of these foods are normally thought of as a "liquid" (e.g., liquid whole egg), a "gas" (e.g., aerosol foods) or "viscous" (e.g. honey, molasses). By definition, catch weight products are also sold by weight.

The following products are required to show their net quantity by weight:

  • products packed for dispensing in aerosol form
  • Honey
  • peanut butter
  • maple butter
  • cooking molasses
  • table molasses
  • fancy molasses
  • cottage cheese
  • Yogurt
  • Dips
  • whipped butter
  • liquid whole egg, egg-yolk or egg albumen or mixtures of two or more of those products
  • frozen liquid whole egg, egg-yolk or egg albumen or mixtures of two or more of those products.


Fluid measure or volume is required for almost all liquids. Section 22(3) CPLR lists the prepackaged products that are required to show their net quantity by volume. Examples include tomato sauce, soup and maple syrup. Some "solid" foods are included in this list (e.g., olives, cherries, pickles), as well as several foods that are not usually thought of as liquids because they are not "pourable" (e.g., jam, sour cream).

Some very viscous liquids (e.g., pudding, oyster sauce) may be declared either by weight, by volume, or by both weight and volume provided both are accurate and not presented in a deceptive manner.

The following products are required to show their net quantity by volume:

  • canned fruits
  • canned vegetables
  • Pickles
  • Relishes
  • Olives
  • creamed mushrooms
  • mushrooms in brine
  • maraschino cherries
  • crème de menthe cherries
  • cocktail cherries
  • beans with pork
  • infant foods
  • junior foods
  • spaghetti in tomato sauce
  • ice cream and products containing ice cream
  • ice milk and products containing ice milk
  • sherbet and products containing sherbet
  • fruit pie filling
  • fountain fruits
  • tomato paste
  • tomato puree
  • Soup
  • condensed soup
  • jam and jam with pectin
  • jelly and jelly with pectin
  • marmalade and marmalade with pectin
  • Preserves
  • frozen liquid foods other than the products described in item 16 of the Table to subsection 22(1)
  • tomato catsup
  • tomato chili sauce
  • tomato sauce
  • tomato pulp
  • tomato juice, concentrated
  • cranberries, cranberry sauce
  • Mincemeat
  • ice cream cake
  • sour cream
  • fruit spreads
  • canned concentrated milk products
  • maple syrup

Drained Weight

Some foods, such as canned shellfish and frozen glazed fish, are packed in brine, water or other liquid that is not normally consumed. Section 22(2) CPLR lists the prepackaged products that are required to show their net quantity by weight of the edible contents in the container (i.e. drained weight). This does not include the free liquid or glaze content.

While a drained weight methodology is used to determine the net quantity declaration of these products, the words "drained weight" are not required in the declaration.

Some legislation, such as the Canada Agricultural Products Act (CAPA), requires a minimum drained weight for certain products in standardized container sizes but requires the net quantity to be stated by volume. For example, Schedule IV of the Processed Products Regulations (PPR) outlines the minimum net and drained weight requirements for lima beans [Schedule IV, Table I, B Canned Vegetables, Item 2, PPR]. However, the net quantity is required to be stated by volume [Schedule V, 4, PPR].

The following information clarifies whether these foods are considered drained weight products:

  • When oysters are packed in oil, both the oysters and the oil is considered to be "edible content", therefore the total weight of the product (i.e. the combined weight of the oysters and oil) must be declared on the label.
  • When vienna sausages are packed in meat stock, the net quantity of the product, excluding the net quantity of the meat stock, must be declared on the label because although the meat stock is edible, it is not intended to be eaten.
  • When sardines are packed in spring water, the net quantity of the product, excluding that of the spring water, must be declared on the label because although the spring water is edible, it is not intended to be eaten.

The following products are required to show their net quantity by weight of the edible contents in the container (i.e. drained weight):

  • canned shellfish
  • canned crustaceans
  • meat packed in brine or vinegar solutions
  • frozen glazed fish

Numerical Count

Canned or frozen corn-on-the-cob is the only food which is required to show its net quantity in terms of numerical count [22(4), CPLR]. However, it is acceptable to declare the net quantity of certain other products by numerical count (e.g., "one dozen donuts" or "one dozen dinner buns").

Established Trade Practices

For a number of products, the method of expressing the net quantity is neither specified in any set of regulations, nor does it follow the general requirement of declaring solid products by weight and liquid products by volume. Section 21 of the CPLR provides for net quantity to be declared according to the established trade practices in these situations. You can find more information on established trade practices for net quantity declarations for foods such as fruit cakes, donuts and popcorn in the table below:

Optional Additional Information

Canadian Units of Measure

Although Canadian (previously named "Imperial") units of measure are not required on labels, they are permitted to be used in addition to the required metric units. When the net quantity is shown in both metric units and Canadian units, the metric units should be declared first and the two units of measure must be grouped together on the label with no intervening material. [17, CPLR].

For example:

500 g net quantity / quantité nette 17.6 oz

Sufficient spacing should be placed between the two declarations to avoid confusion. However, they need not appear on the same horizontal line. The Canadian declaration may be placed below the metric declaration.

For example:

114 ml
4 oz fl


114 ml 4 oz fl

"Fluid ounces" and "ounces" are not the same in Canadian units and therefore are not interchangeable. If Canadian units are used, fluids such as coffee and soft drinks must always be described as "fluid ounces" rather than "ounces".

The following conversions may be used:

1 fl oz Canadian = 28.413 ml
1 oz = 28.350 g

U.S. (American) Units

U.S. (American) units of measure may also be used on labels provided that an appropriate and accurate metric net quantity is declared. This may be instead of or in addition to the Canadian measure.

There is a difference between U.S. and Canadian fluid measure. The U.S. fluid ounce is slightly larger than the Canadian fluid ounce:1 fl oz U.S. = 1.041 fl oz Canadian = 29.574 ml.

With the exception of the fluid ounce measure, the U.S. measure is smaller than the Canadian measure. For this reason, all U.S. units of volume, except for the fluid ounce, may be shown in addition to the metric units provided that the U.S. units are identified as "U.S." This distinction is not necessary in cases where the U.S. unit is equal to or larger than the corresponding Canadian measure (e.g., in the case of U.S. fluid ounces) because Canadian consumers would receive at least as much as they expect. Non metric declarations (e.g., fluid ounces, pounds, quarts, etc. ), if shown, may be in English or French.

Canada and U.S. Alternate units of Measurement
MeasureAlternate measureRounded Metric
1 Canadian pint 20 Canadian fluid ounces 568 ml
1 U.S. pint 16 U.S. fluid ounces 473 ml
1 Canadian quart 40 Canadian fluid ounces 1.14
1 U.S. quart 32 U.S. fluid ounces 946 ml
1 Canadian gallon 160 Canadian fluid ounces 4.55
1 U.S. gallon 128 U.S. fluid ounces 3.78

European "e" Symbol

This symbol is used by some countries in the European Union to indicate an average net weight system. It is acceptable to use the European Union symbol "e" alongside a net quantity declaration on imported products, provided that all net quantity requirements are met.


Qualification of the net quantity declaration is defined as "false and misleading" under paragraph 7(2)(a) of the CPLA and therefore prohibited. Examples of qualified net quantities include "big Litre", "full litre", "approximately" and "average weight". Other representations likely to deceive the consumer with respect to the net quantity of a prepackaged food are also prohibited.

Supplementary Information

Supplementary net quantity information is considered voluntary on food products. However, once a company chooses to place such information on a food label, it must ensure that the statement is not likely to deceive a consumer with respect to the net quantity of a prepackaged product.

For example, although cookies are required to be sold by weight, supplementary information such as a net quantity statement by count giving either the true count, for example, "12 cookies", or a non-precise indication of the minimum count of cookies present is acceptable. Examples of supplementary minimal count information: "at least 12 cookies", "not less than 12 cookies", "more than 12 cookies", "12-14 cookies" "number of cookies may vary from 12 to 14 cookies". In these examples, every package must contain at least 12 cookies and the net quantity by weight must meet the applicable regulatory requirements.

Indications such as "approximately" are too ambiguous and do not indicate a minimum that the consumer could expect, therefore, "approximately" is not an appropriate term.

This supplementary information is not deemed to be a declaration of the number of servings for the application of section 8 of the Consumer Packaging and Labelling Act (CPLA).
