Understanding Protein Quality: PDCAAS and Why It Matters
high-protein foods for vegetarians in Canada Before the list, one brief explanation that makes a significant practical difference: not all protein is equal. The Protein Digestibility-Corrected Amino Acid Score (PDCAAS) measures how completely a protein source provides all nine essential amino acids that the human body cannot produce independently. Animal proteins typically score 1.0 (the maximum). Some plant proteins — particularly soy-based foods — also score 1.0. Others score lower, meaning they provide less complete amino acid coverage per gram of protein consumed.
This does not make lower-scoring plant proteins bad. It means they are most nutritionally effective when combined with complementary protein sources throughout the day — a principle that does not require eating specific food combinations at every meal, but does support the value of dietary variety. The foods on this list are ranked partly by protein content and partly by PDCAAS and overall nutritional profile, reflecting current Canadian dietary science recommendations.
Tofu — The Most Versatile High-Protein Vegetarian Staple
Protein: 8–10g per 100g | PDCAAS: 1.0 (complete protein) Available at: Every major Canadian supermarket; Loblaws, Sobeys, Metro, T&T, No Frills
Tofu is the single most nutritionally efficient plant-based protein available in Canadian grocery stores. With a PDCAAS of approximately 1.0 from soy — the highest possible score — tofu provides a complete amino acid profile equivalent to animal protein, at a price point that makes it accessible to virtually every household. It is widely available in Canadian grocers and requires minimal prep.
The three main varieties suit different cooking applications. Firm tofu holds its shape during stir-frying, grilling, and baking — it is the format to press, cube, marinate, and use as a meat substitute in curries, stir-fries, and tofu scrambles. Silken tofu is blended into smoothies, soups, sauces, and desserts for a protein boost that is entirely invisible in texture. Extra-firm tofu is the best choice for crispy pan-frying or air-frying — when pressed thoroughly to remove excess water, it develops the closest texture to pan-fried chicken.
Canadian brands to look for: Sunrise Soya Foods (BC-based), Silken Tofu by Sunrise, and local fresh tofu from Asian grocery stores across Vancouver, Toronto, and Calgary.
Lentils — The Most Affordable Protein in Canada
Protein: 9g per 100g cooked | PDCAAS: ~0.6 (pair with grains) Available at: Every Canadian supermarket; bulk food stores; very affordable
Canada is one of the world’s largest producers of lentils — Saskatchewan and Manitoba together grow approximately 30–40% of global lentil supply — which makes lentils not merely a nutritious vegetarian protein choice for Canadians but a genuinely patriotic one. They are also among the most affordable protein sources available anywhere in the country, even as food prices have risen significantly.
A 100g cooked serving of lentils provides 9g of protein alongside 8g of dietary fibre, folate, iron, and potassium — a nutritional profile that explains why the Canada Food Guide specifically promotes lentils as a primary protein food. The fibre content produces a slow, sustained release of energy and exceptional satiety, making lentils one of the most effective foods for weight management without calorie restriction.
PDCAAS is lower than soy-based proteins (~0.6), but this is easily compensated by eating lentils alongside rice, bread, or other grain-based foods throughout the day — the combination of legume and grain amino acid profiles is nutritionally complete.
Best varieties for Canadian cooking: Red lentils (cook quickly, ideal for dals and soups), green lentils (hold shape, good for salads and side dishes), French Puy lentils (premium, nutty, available at most Canadian supermarkets).
Greek Yoghurt — The Highest-Protein Dairy Option
Protein: 10g per 100g (plain, non-fat) | PDCAAS: ~1.0 Available at: All Canadian supermarkets; Oikos, Liberté, and Stonyfield brands widely available
Greek yoghurt achieves its higher protein content through straining — removing the liquid whey concentrates the protein in the remaining solid, producing approximately double the protein of regular yoghurt. A 175g serving of plain Greek yoghurt typically provides 17–20g of protein alongside calcium, probiotics, and B vitamins, making it one of the most nutritionally dense dairy foods available.
The important buying advice: always choose plain, unsweetened Greek yoghurt. Flavoured versions frequently contain 15–25g of added sugar per serving — enough to undermine the nutritional value of the protein content. Canadian brands Oikos and Liberté both produce excellent plain Greek yoghurt widely available at Loblaws, Sobeys, and Metro. The PC (President’s Choice) plain Greek yoghurt from Loblaws is consistently good quality at a competitive price.
For vegans: Coconut yoghurt is the closest alternative but typically provides only 2–4g protein per serving — considerably less than dairy Greek yoghurt. A better vegan alternative for protein density is soy-based yoghurt, which typically provides 6–8g per serving.
Tempeh — The Fermented Soy Protein Superior to Tofu
Protein: 19g per 100g | PDCAAS: ~1.0 Available at: Whole Foods, health food stores, and increasingly at major Canadian supermarkets
Tempeh is arguably the most nutritionally impressive vegetarian protein food available in Canada — and the one that most vegetarians underuse. Made from fermented whole soybeans pressed into a firm cake, tempeh contains nearly twice the protein of tofu per 100g (approximately 19g vs 10g), while the fermentation process enhances the bioavailability of the protein and significantly improves digestibility compared to unfermented soy.
Fermentation also produces beneficial probiotics, reduces the phytic acid that inhibits mineral absorption in unfermented beans, and creates the characteristic earthy, nutty flavour that makes tempeh one of the most flavourful plant proteins available. It absorbs marinades exceptionally well, holds its shape during cooking better than tofu, and produces a satisfying chewy texture when sliced and pan-fried.
Where to find it in Canada: Whole Foods carries multiple tempeh brands nationally. Lightlife — a Canadian brand now owned by Maple Leaf Foods — is the most widely distributed and available at most major supermarket chains. PC Organics tempeh is available at Loblaws.
Edamame — The Snack That Doubles as a Protein Source
Protein: 11g per 100g cooked | PDCAAS: ~1.0 Available at: Frozen section of all major Canadian supermarkets; very affordable
Edamame — whole, young soybeans — are the most convenient complete plant protein available in frozen form. A 150g serving of cooked edamame provides approximately 17g of protein with a full amino acid profile, making it one of the most protein-dense snacks available without any preparation beyond boiling or microwaving for five minutes.
Beyond the protein, edamame provides meaningful amounts of fibre, folate, vitamin K, and iron — making it a significantly more nutritious snack than most processed alternatives. It is the complete protein snack that the Canadian fitness community has been somewhat slow to adopt compared to its popularity in the USA and the UK, but its frozen availability at every major supermarket chain makes it one of the most accessible high-protein options in the country.
Best way to eat it: Boiled or microwaved from frozen, sprinkled with sea salt, eaten as a snack or side dish. Also excellent in grain bowls, salads, and stir-fries.
Cottage Cheese — The Underrated Casein Protein Powerhouse
Protein: 11–12g per 100g | PDCAAS: ~1.0 Available at: All Canadian supermarkets; Nordica, Sealtest, Breakstone’s brands
Cottage cheese has experienced a significant resurgence in popularity across North American nutrition culture in 2025–2026, driven partly by social media and partly by the genuine nutritional case for a food that has been unfashionably overlooked for decades. A 200g serving of low-fat cottage cheese provides approximately 23g of protein — primarily casein, a slow-digesting dairy protein that produces a sustained, gradual release of amino acids that makes it particularly effective for muscle recovery and overnight protein synthesis.
For Canadian vegetarians who include dairy, cottage cheese is one of the highest protein-per-dollar foods available in the country. Nordica and Sealtest are the most widely distributed Canadian brands, available at every major supermarket. The PC brand from Loblaws is an affordable and consistent alternative.
How to use it: Eaten plain with fruit or honey, blended into smoothies for a creamy protein boost, spread on toast with avocado, or used as a high-protein substitute for ricotta in lasagne or stuffed pasta.
Quinoa — The Only Complete Grain Protein
Protein: 4g per 100g cooked (8g per 100g dry) | PDCAAS: ~0.9 Available at: All Canadian supermarkets; bulk food stores
Quinoa holds a unique position in the vegetarian protein landscape: it is the only widely available grain that provides a near-complete amino acid profile, containing all nine essential amino acids in meaningful quantities. This makes it considerably more nutritionally valuable as a protein source than rice, pasta, or bread — foods that provide some protein but lack the amino acid completeness needed to meet daily requirements on their own.
A 185g serving of cooked quinoa provides approximately 8g of protein alongside a meaningful amount of fibre, iron, magnesium, and manganese. As a side dish that replaces less nutritious starches — white rice, white pasta — it simultaneously increases the protein and micronutrient content of a meal while providing the same comfort and satiety.
Canadian buying tip: Bob’s Red Mill quinoa is widely available at Canadian supermarkets and is typically the most affordable option. Bulk food stores including Bulk Barn offer quinoa at lower per-kilogram cost than pre-packaged options.
Black Beans — The Budget Protein with Exceptional Fibre
Protein: 8–9g per 100g cooked | PDCAAS: ~0.75 Available at: Every Canadian supermarket, both canned and dried; very affordable
Black beans are an inexpensive source of protein and can be prepared in various ways, making them a very versatile ingredient when preparing meals. For Canadian vegetarians watching food costs — a consideration that has become increasingly important during the inflation period of 2024–2026 — black beans represent one of the strongest protein-per-dollar values available anywhere in the grocery store.
A 175g serving of black beans provides approximately 15g of protein alongside 12g of fibre — a fibre content that supports gut health, cardiovascular health, and satiety in ways that most other protein sources cannot match simultaneously. The combination of protein and fibre makes black beans one of the most effective single foods for maintaining a healthy weight without counting calories.
Best ways to use them: Black bean tacos, burrito bowls, chilli, soups, and salads. Canned black beans (no-salt-added varieties from PC or No Name brands at Loblaws) require zero preparation beyond rinsing and draining — making them one of the most convenient plant-based protein additions to any meal.
Eggs — The Gold Standard of Bioavailability
Protein: 6g per large egg (13g per 100g) | PDCAAS: 1.0 Available at: Every Canadian supermarket, farm markets, and convenience stores
For vegetarians who include eggs — the largest segment of the Canadian vegetarian population — eggs are the single most bioavailable protein source available anywhere. The PDCAAS of 1.0 reflects a complete amino acid profile in proportions closely matched to human requirements, and the digestibility of egg protein is exceptionally high compared to most plant proteins.
A two-egg serving provides approximately 12g of complete protein alongside healthy fats, choline (critical for brain function), vitamin D, and vitamin B12 — a nutrient that vegetarians who do not consume meat need to obtain from animal-derived foods. The nutritional case for eggs in a vegetarian diet is one of the strongest in Canadian nutritional science.
Canadian buying tip: Free-run and free-range eggs are widely available at Canadian supermarkets at a modest premium over standard eggs. Egg Farmers of Canada certification indicates Canadian-produced eggs — the freshest available in Canadian supermarkets.
Hemp Seeds — The Canadian Superfood Protein
Protein: 31g per 100g (10g per 30g serving) | PDCAAS: ~0.6-0.7 Available at: Most Canadian supermarkets, Costco, health food stores
Canada is the world’s leading producer of hemp — a crop that has been grown in the Prairie provinces for decades and whose seeds are among the most nutritionally impressive foods available. Hemp seeds (also called hemp hearts when hulled) provide approximately 31g of protein per 100g — one of the highest protein densities of any plant food — alongside an exceptional ratio of omega-3 to omega-6 fatty acids, and significant amounts of magnesium, zinc, and iron.
Three tablespoons (30g) of hemp seeds sprinkled on oatmeal, yoghurt, salad, or smoothies provides approximately 10g of protein with zero cooking required. This “sprinkle-on” convenience makes hemp seeds one of the most practical protein additions for busy Canadian professionals who want to increase their daily protein intake without restructuring their meals.
The PDCAAS is moderate rather than exceptional (~0.6–0.7), but the omega-3 content — which most vegetarian diets often lack — gives hemp seeds a nutritional value beyond raw protein content. Manitoba Harvest is the most widely distributed Canadian hemp seed brand and is available at most major supermarket chains.
How to Hit Your Daily Protein Target as a Vegetarian in Canada
The most practical advice for vegetarians trying to hit their protein targets is surprisingly simple: build every meal around a protein anchor first. The common mistake is treating protein as an afterthought — adding it to a meal that is already built around starch or vegetables. Reverse the planning order: decide on the protein source, then build the rest of the meal around it.
A sample 100g protein day for a Canadian vegetarian:
- Breakfast: Greek yoghurt (175g, ~17g protein) + hemp seeds sprinkled on top (30g, ~10g protein)
- Lunch: Lentil soup with whole grain bread (250g lentils, ~22g protein)
- Snack: Edamame (150g, ~17g protein)
- Dinner: Tofu stir-fry with quinoa (150g firm tofu + 185g quinoa, ~18g + 8g protein)
- Total: approximately 92g protein
Adding a two-egg scramble to breakfast, or a serving of cottage cheese as an evening snack, easily brings the total to 100g+ — the target for a 65kg adult doing moderate exercise. Most adults do well with 20–40g of protein per meal, depending on body size and goals. Plant proteins can meet these needs affordably when paired strategically — for example, tofu plus grains, or legumes plus seeds, to balance amino profiles across the day.
Final Thoughts: Vegetarian Protein in Canada Is Easier Than You Think
The top 10 high-protein foods for vegetarians in Canada on this list are not exotic, expensive, or difficult to find. Every one of them is available at major Canadian supermarket chains — Loblaws, Sobeys, Metro, Costco, and Whole Foods — at prices that are competitive with or cheaper than equivalent animal protein sources. Lentils, black beans, tofu, and edamame are specifically among the most affordable foods in the Canadian grocery store, making a high-protein vegetarian diet accessible at every income level.
The key insight from the Canada Food Guide’s current recommendations is that plant-based proteins are not a compromise — they are a recommendation. Include foods such as beans, lentils, nuts, seeds, and plant-based proteins as a primary dietary choice, not as a fallback when meat is unavailable. Your body — and Canada’s extraordinary pulse and legume production sector — will thank you for it.
