Have you ever wondered whether to write odor or odour in Canada? You are not alone. Both spellings are correct, and both refer to a smell. However, the preferred spelling depends on the type of English you are using.
In Canadian English, odour is generally the preferred spelling because Canadian spelling traditionally favours the -our ending in words such as colour, honour, and flavour. The spelling odor is standard in American English and is also understood in Canada. Canada’s Language Portal recommends odour for Canadian writing. <Cite refs={[“turn918900search0″,”turn918900search1”]}/>
If you are writing a school assignment, blog post, business document, or article for a Canadian audience, choosing odour is usually the best option. The most important thing is to follow your chosen spelling style consistently.
What Is the Difference Between Odor and Odour?
The main difference between odor and odour is spelling, not meaning. Both words describe a smell that a person can detect through the nose. The smell may be pleasant, unpleasant, weak, or strong.
The word odour is commonly preferred in Canadian and British English, while odor is the standard American spelling. For example, a Canadian writer might describe the odour of fresh flowers, while an American writer would usually describe their odor. Both sentences communicate the same idea. <Cite refs={[“turn918900search4″,”turn918900search6”]}/>
Odour: Canadian English
Odour is the recommended choice for most Canadian writing. It follows the traditional Canadian preference for words ending in -our rather than the American -or.
Examples:
- The odour of fresh bread filled the kitchen.
- A strange odour came from the basement.
- The flowers released a pleasant odour.
- The strong odour of garbage spread across the street.
- The bathroom had an unpleasant odour.
Use odour when writing Canadian-focused blog articles, educational content, formal documents, and general informational material.
Odor: American English
Odor is the usual American English spelling. It has the same meaning as odour and is widely recognized by English speakers in Canada.
Examples:
- The odor of fresh coffee filled the room.
- An unusual odor came from the refrigerator.
- The product helps control body odor.
- The odor disappeared after cleaning.
- The laboratory measured the odor of the chemical.
Use odor when following American English spelling conventions or when reproducing a product name, quotation, or official title that uses that spelling.
Which Spelling Should You Use in Canada?
If you are writing for Canadian readers, choose odour unless your organization, publication, or client requires American spelling. This recommendation follows guidance from Canada’s Language Portal, which generally favours -our endings in words such as odour. <Cite refs={[“turn918900search0″,”turn918900search1”]}/>
For example, a Canadian blog post should normally use the following sentence:
The unpleasant odour coming from the drain made the kitchen uncomfortable.
An American publication would more commonly write:
The unpleasant odor coming from the drain made the kitchen uncomfortable.
Both sentences are grammatically correct. The difference reflects regional spelling preferences rather than a difference in meaning.
Canadian English includes both British and American spelling conventions, so not every word follows the same pattern. A reliable Canadian dictionary or your organization’s style guide can help you decide which spelling to use. <Cite refs={[“turn918900search1″,”turn918900search3”]}/>

What Does Odour Mean?
The noun odour means a smell or scent that can be detected by the sense of smell. It can describe something pleasant, such as fresh flowers, or something unpleasant, such as spoiled food.
The word often appears in everyday conversations, product descriptions, scientific writing, and discussions about household cleanliness. Although people frequently use it to describe bad smells, an odour is not always unpleasant. <Cite refs={[“turn918900search6″,”turn918900search10”]}/>

What Are the Different Types of Odour?
Odours can be described according to their source, strength, and character. The following examples show how the word is used in everyday English.
1. Pleasant Odour
A pleasant odour is a smell that people generally find enjoyable. Flowers, perfumes, fresh food, and scented candles can produce pleasant odours.
Example: The pleasant odour of roses filled the garden.
2. Unpleasant Odour
An unpleasant odour is a smell that people generally dislike. Common examples include spoiled food, stagnant water, and unclean garbage bins.
Example: An unpleasant odour came from the garbage container.
3. Musty Odour
A musty odour is a stale smell often associated with damp or poorly ventilated spaces. It may occur in basements, closets, or rooms where moisture has accumulated.
Example: The old cupboard had a musty odour.
4. Body Odour
Body odour refers to the smell associated with the human body. It can develop when bacteria break down substances in sweat on the skin.
Example: Regular washing can help manage unwanted body odour.
5. Chemical Odour
A chemical odour is a smell associated with a chemical substance or product. Some chemicals can be harmful even when their smell is faint or absent.
Example: The worker noticed a chemical odour near the storage area.
If you detect a sudden, unexplained chemical or fuel-like smell, avoid trying to identify it by sniffing closely. Leave the area if you suspect a hazardous leak and contact the appropriate emergency or safety service.
Odour or Odor in Canadian English: Common Mistakes
Writers sometimes assume that one spelling is correct everywhere. In reality, regional English conventions influence many common words.
Here are several mistakes to avoid when choosing between odour and odor.
- Assuming odor is always incorrect: It is a standard American spelling, not a misspelling.
- Using both spellings in one article: Pick one spelling style and maintain consistency.
- Confusing spelling with meaning: Both forms describe the same thing.
- Ignoring your audience: Canadian readers generally expect Canadian spelling in locally focused content.
- Changing official wording: Preserve the original spelling in direct quotations, brand names, and official titles.
Remember that Canadian English is not identical to British or American English. It combines conventions from both, so checking a Canadian reference is useful when a spelling question arises. <Cite refs={[“turn918900search1″,”turn918900search3”]}/>
Related Words: Odour, Odorous, and Odourless
The spelling can change when a suffix is added to odour. This is an important detail for writers who want to avoid spelling mistakes.
| Word | Meaning | Example |
| Odour | A smell | The odour was noticeable. |
| Odorous | Having or producing a smell | The odorous material was removed. |
| Odourless | Having no noticeable smell | The odourless liquid was stored safely. |
| Odorant | A substance that produces or adds a smell | The odorant makes the gas detectable. |
| Odoriferous | Producing or carrying a noticeable smell | The odoriferous plants grew near the path. |
Important Canadian spelling rule: Although odour is generally preferred, the u is dropped in words such as odorous and odorant. Therefore, write odorous, not odourous. Canada’s Language Portal specifically explains this spelling pattern. <Cite refs={[“turn918900search0″,”turn918900search9”]}/>
Odor or Odour in Canada: Which One Is Best for SEO?
