Grades and Grade Names

2. There are four grades of eggs with the grade names Canada A, Canada B, Canada C and Canada Nest Run (See Volume 9 Import Grade Requirements should include for grade names used for imported eggs).

3. (1) A prepackaged egg that meets the grade requirements must bear the applicable grade name as shown in the Egg Grade Names Schedule.

(2) The grade name referred to in section 2 must be displayed on prepackaged eggs:

  • (a) in the case of a tray with an overwrap or a carton, on the top of the tray or carton; and
  • (b) in the case of a container, other than a tray with an overwrap or a carton, in a central location on the container, except the top or the bottom.

(3) Despite paragraph (2)(a), the grade name is not required to be shown on trays with an overwrap or on cartons that are packaged in another container (referred to as an "outer container") if the grade name is shown on the outer container which is sent or conveyed to an establishment in which a licence holder is authorized under the Act to grade, package, and label eggs.

(4) Despite paragraph (2)(b), if consumer prepackaged eggs graded and labelled pursuant to this Volume, are packaged in another container (referred to as an "outer container"), the grade name is not required to be shown on the outer container if the grade name is

  • (a) visible and easily legible without opening the outer container; and
  • (b) not obscured by the outer container.

(5) The grade name referred to in section 2 must be shown:

  • (a) in the case of a container, other than a tray with an overwrap or a carton, that contains eggs graded Canada A or Canada B, in characters not less than
    • (i) 6 mm in height for the word "Canada", and
    • (ii) 13 mm in height for "A" or "B", as the case may be;
  • (b) in the case of a tray with an overwrap or a carton of eggs graded Canada A or Canada B, in characters of not less than
    • (i) 1.5 mm in height for the word "Canada", and
    • (ii) 3 mm in height for "A" or "B", as the case may be;
  • (c) in the case of a container other than a tray with an overwrap or a carton, that contains eggs graded Canada C or Canada Nest Run, in characters not less than 13 mm in height; and
  • (d) in the case of a tray with an overwrap or a carton of eggs graded Canada C or Canada Nest Run, in characters not less than 1.5 mm in height.

(6) The size designation referred to in section 5 must be shown

  • (a) in the case of a tray with an overwrap or a carton, in characters of not less than 3 mm in height, and
  • (b) in the case of a container other than a tray with an overwrap or a carton, in characters not less than 13 mm in height.

Canada A

4. (1) An egg graded Canada A must

  • (a) show, on candling
    • (i) a reasonably firm albumen,
    • (ii) an indistinct yolk outline,
    • (iii) a round yolk that is reasonably well centered, and
    • (iv) an air cell that is not in excess of 5 mm in depth;
  • (b) have a shell that
    • (i) has not more than three stain spots, the aggregate area of which does not exceed an area equivalent to 25 mm2 and is otherwise free of dirt and stain,
    • (ii) is normal or nearly normal in shape but may have rough areas and ridges other than heavy ridges, and
    • (iii) is uncracked; and
  • (c) be also graded for size, as set out in section 5.

(2) Despite subsection (1), if an inspector, before grading, inspects a sample from a lot, the eggs in that lot must not be graded as Canada A unless the sample meets the following requirements

  • (a) the quality factor of albumen firmness of the eggs in the sample averages 67 Haugh units or higher;
  • (b) the sample does not contain more than
    • (i) 10% of eggs with cracked shells;
    • (ii) 5% of eggs with dirt on the shells if the dirt on the shell is more than 160 mm2 in size but covers less than 1/3 of the area of the shell;
    • (iii) 2.5% of eggs with dirt on the shells if the dirt covers 1/3 or more of the area of the shell;
    • (iv) 5% of eggs with stains on the shells if the stains cover more than 1/2 the area of the shell;
    • (v) 10% of eggs with rough, ridged or misshapened shells;
