CFIA Rounding Rules for Nutrition Facts Tables

Canadian nutrition labels require specific rounding for every nutrient. Each nutrient has its own threshold bands and rounding increments — there are over 40 individual rules across calories, macronutrients, minerals, and vitamins. Getting even one wrong makes your label non-compliant.

These rules are defined in the Food and Drug Regulations (FDR) and the CFIA Nutrition Facts table guidance. Last verified against the live CFIA website.

Serving size (metric measure)

Range	Round to
Less than 10 g or 10 mL	Nearest 0.1 g or 0.1 mL
10 g or 10 mL or more	Nearest 1 g or 1 mL

Nutrient rounding rules

Calories (kcal)

Less than 5	Express as 0
5 to 50	Nearest 5
More than 50	Nearest 10

Fat (Total) (g)

DV: 75 g. %DV rounded to nearest 1%.

0.05 to 0.49 mg	Nearest 0.1 mg
0.5 to 2.49 mg	Nearest 0.25 mg
2.5 mg or more	Nearest 0.5 mg

Vitamin A (µg RAE)

0.1 to 0.99 mg	Nearest 0.2 mg
1 to 4.99 mg	Nearest 0.5 mg
5 mg or more	Nearest 1 mg

Vitamin D (µg)

DV: 20 µg. %DV rounded to nearest 1%.

Less than 0.1 µg	Express as 0 µg
0.1 to 0.99 µg	Nearest 0.2 µg

5 µg or more	Nearest 1 µg

Key differences from US FDA rounding

≠Fat 0.5–5g rounds to nearest 0.5g in Canada, nearest 1g in the US

≠Cholesterol has no %DV in Canada (amount only) — US shows %DV

≠Carbohydrate and Protein have no %DV in Canada — US shows %DV for both

≠Saturated + Trans fat share one combined %DV in Canada — US shows separate %DV

≠Potassium, Calcium, and Iron use multi-band rounding in Canada — US uses simpler rules

≠Vitamin A, C, D use 4-band rounding in Canada — US uses 2-band

≠Different Daily Values entirely (e.g., Iron: 18mg Canada vs 18mg US, but Fat: 75g Canada vs 78g US)

Why manual rounding doesn't work

With over 40 individual rounding rules across 16+ nutrients — each with different threshold bands, different precision requirements, and different %DV calculations — manual rounding using a spreadsheet is practically guaranteed to produce errors. A single nutrient like Potassium has 4 rounding bands. Iron has 4. Vitamin A has 4. And each band has a different rounding increment.

This is why tools built for the Canadian market exist — to apply all of these rules automatically and consistently, every time.
