Thanksgiving dinner is behind us, Halloween candy is everywhere and the holiday season is on its way. If rich food leaves you bloated, tired or foggy, you might be wondering how to actually get a food sensitivity test in Canada. There's no single test that covers everything. Instead there are a few routes: your family doctor, an allergist, a registered dietitian, a naturopathic doctor, and an at-home food sensitivity test. This guide walks through what each one can and can't do, what's usually covered, and how they fit together.
Allergy, intolerance or sensitivity?
It helps to know which question you're asking. A food allergy involves the immune system, usually comes on quickly (often within minutes) and can be serious. A food sensitivity or intolerance tends to build more slowly, often hours after eating, and shows up as everyday discomfort: bloating, gas, stomach cramps, diarrhea, headaches, tiredness or brain fog.
True allergies are only around 10% of reactions to food. Intolerances and sensitivities are the main cause of the everyday discomfort people put up with, which is why most Canadians looking into their symptoms start there. Our guide to recognising the symptoms of food intolerance and our symptoms page list the common signs.
Whatever you find out, reading labels helps. In Canada, prepackaged food must declare the priority allergens and gluten sources, either in the ingredient list or in a "Contains" statement right after it. The Canadian Food Inspection Agency explains how allergen labelling works, from milk, eggs, wheat and soy to mustard, sesame and sulphites.
If you ever have swelling of the lips, tongue or throat, trouble breathing, or feel faint after eating, that's an emergency: call 911.
Route 1: your family doctor (or a walk-in clinic)
Your family doctor is the right first stop, mainly to rule out anything that needs medical care. If you don't have one, a walk-in clinic or a virtual care service in your province can help. Depending on your symptoms, they may:
- Check for celiac disease. Celiac disease is an autoimmune condition, not an intolerance, but the symptoms overlap. It starts with a blood test, and you need to keep eating gluten until you've been tested, because cutting it out first can affect the result.
- Look at lactose. They may suggest a short trial without dairy, or refer you for a breath test.
- Talk about IBS. If your symptoms point to irritable bowel syndrome, they may suggest diet changes such as the low FODMAP approach.
- Refer you to an allergist if you've had fast reactions such as hives or swelling.
What's covered. Visits to a family doctor, walk-in clinic or a referred specialist are covered by your provincial or territorial health plan (OHIP in Ontario, MSP in British Columbia, RAMQ in Quebec and so on). The catch is often the wait, especially for an allergist.
What a family doctor usually can't do is give you one test that lists everything you're sensitive to. For everyday sensitivities, the next step is usually a food diary and a dietitian.
Route 2: a registered dietitian
Registered dietitians (RD, or Dt.P. in Quebec) are regulated in every province. You can usually book one directly, without a referral, and many workplace extended health benefit plans cover part of the fee. Some provinces and family health teams also offer free dietitian advice.
A dietitian will usually start with your food and symptom diary, then guide you through an elimination diet: cutting out suspected foods for a few weeks, then bringing them back one at a time to see what happens. It works, but it's slow, and it's much easier when you know where to start.
Start your diary now, whichever route you choose. Our free food and symptom diary template makes it easy.
Route 3: a naturopathic doctor
Many Canadians also see a naturopathic doctor (ND). NDs are regulated in several provinces, including British Columbia and Ontario, and their visits are often covered in part by extended health benefits. Some offer blood-based food sensitivity panels, which usually come with a clinic fee on top of the consultation. If you're weighing a blood panel against a hair sample, our guide to hair vs blood food sensitivity tests explains the differences.
Route 4: an at-home hair sensitivity test
This is where many of our Canadian customers start, because it gives you a shortlist to take to your diary and your dietitian, without a wait. It works differently from anything your doctor orders. It doesn't use blood or measure antibodies. You send a small hair sample, and our testing team uses bioresonance to look for potential sensitivity patterns across hundreds of food and non-food items, such as additives, metals and environmental items. Our guide to how hair sensitivity testing works explains the method.
In Canada our tests come with digital instructions: you get a link by email, cut a small hair sample and mail it to us in your own envelope. Here's what you're ordering with digital instructions and what happens after you send your hair sample. Results arrive in 5–7 working days once your sample is received.
If you'd like the widest range of items, the Optimum Sensitivity Test checks 1,600. If you'd rather start smaller, the Individual Sensitivity Test checks 600.

Testing the whole family before the holidays? The Ultimate Individual Test and the Optimum test both come in 2- and 4-person versions, which work out cheaper per person. Not sure which level suits you? Our guide to comparing food sensitivity tests explains the differences, so we won't repeat it here.
A sensible order of steps
- See your family doctor (or a walk-in clinic) to rule out anything that needs medical attention, including celiac disease (keep eating gluten until you've been tested).
- Start a food and symptom diary straight away and keep it going for a few weeks.
- Take an at-home food sensitivity test if you'd like a shortlist of potential sensitivities to explore.
- Compare your results with your diary and look for foods that appear in both.
- Trial changes one food at a time, ideally with a registered dietitian, so you keep your diet balanced.
Common questions
Can my family doctor test for food sensitivities? Your doctor can check for conditions that look like sensitivity, such as celiac disease, and may arrange a breath test for lactose or refer you to an allergist. There isn't one standard test for everyday food sensitivities, so most people combine a food diary with a dietitian, and many add an at-home test as a starting point.
Is food sensitivity testing covered by OHIP or my provincial plan? Doctor and specialist visits are covered by your provincial or territorial plan. At-home tests aren't covered and are paid for yourself, though it's worth checking whether your extended health benefits help with dietitian or naturopath visits.
How long do results take? Results arrive in 5–7 working days once your sample is received. Mail time is separate.
What if I'm not happy? We offer a 30-day 100% money-back guarantee on hair sensitivity tests.

About our tests
Test My Food Sensitivity has offered at-home hair sensitivity tests since 2008. Our tests use bioresonance, which looks at energetic frequencies from a hair sample to identify potential sensitivity patterns. They don't measure immune antibodies (IgE or IgG) and they aren't a medical diagnosis. Use your personalized results as a starting point for exploration, and talk to your family doctor or a registered dietitian before making big or long-term changes to your diet.
