What the Canadian allergen table represents
This guide uses the validated Subway Canada snapshot whose allergen document is dated June 10, 2026. The table contains component records such as breads, sauces, cookies, and other menu building blocks. It is useful evidence, but it is not a finished-order certificate. The Subway Canada menu directory and nutrition page describe the broader menu and nutrition context separately.
A component record answers a narrow question about the source row. It does not automatically reveal every ingredient assembled into a sandwich, salad, bowl, or meal, nor does it prove the exact portion or preparation at one restaurant. For that reason, a component status should never be promoted into a complete prepared-item conclusion without an official mapping.
Contains, may-contain, unknown, and refined-oil-note
`contains` is a source-declared presence for the named allergen in that component. For example, the Ciabatta record reports Wheat as `contains`. That statement belongs to the Ciabatta component; it does not describe every sandwich made with or without Ciabatta.
`may-contain` keeps the source conditional language. Ciabatta reports Milk/Lactose as `may-contain`, which is not the same as a confirmed ingredient presence and is also not permission to treat the bread as safe. The uncertainty is part of the record.
`unknown` means the validated record does not establish a status. The Gluten-Free Bread record reports Egg as `unknown` and has many other unknown fields. Its product name does not turn those unknowns into “free from,” and it does not establish a restaurant-level cross-contact control.
`refined-oil-note` is a special source note and must remain distinct from both `contains` and `unknown`. It is not a universal allergy-free claim. The table also uses these exact labels rather than silently converting them into a simplified safe/unsafe score.
Four examples from the dated records
The Ciabatta row shows Wheat as contains and Milk/Lactose as may-contain. Peppercorn Ranch Sauce shows Egg as contains and Milk/Lactose as contains. These values are component-level evidence and should be quoted with the component name and source date.
Chocolate Chunk Cookie reports Peanuts as may-contain, along with several other declared or conditional statuses. A cookie record cannot be used to infer the status of an entire meal, and the reverse is also true: a prepared-item label cannot erase a component-level warning.
Use the nutrition disclaimer alongside the table. It explains why rounded source values, availability, customization, and medical or allergen questions need separate interpretation.
Why restaurant handling is a separate question
Even a clearly labeled component does not describe the work surface or tools used for a particular order. Shared ovens, toasters, knives, cutting boards, gloves, ingredient bins, and preparation counters can create cross-contact questions that are not represented by a single component row. Restaurant practices can also vary by location, shift, equipment, and requested customization.
Ask the restaurant what current procedures apply to your order, whether dedicated tools are available, and which ingredients or sauces will be handled on the same surface. Do not treat an employee response as a medical guarantee; use it as current operational information alongside the official table and your own clinician-approved plan.
A careful way to use the official information
Start with the exact Canadian menu item and component names. Check the current official allergen and ingredient materials, note the document date, and keep every `unknown` value visible. Then ask about the restaurant’s handling for the actual order, including bread, toppings, sauces, utensils, and work surfaces.
The Subway calorie calculator can help identify the exact menu rows selected for a nutrition estimate, but calories cannot certify allergen safety. Keep a component separate from a prepared item so the calculation does not imply a recipe or preparation guarantee.
If the official material does not answer a question, record it as unknown and contact Subway or the restaurant through current official channels. This independent site is not affiliated with or endorsed by Subway, does not certify orders, and does not replace medical advice.
