CanadaHow We Rate
Every product on this site gets a score from 0 to 10. It is calculated the same way for every product, from two things Amazon.ca shows publicly: the average star rating and how many customers left a rating. A higher commission never changes a score.
How we choose products
For each category we start with the best-selling and highest-rated products on Amazon.ca, keep only established brands, and leave out renewed items, bundles and listings with very few reviews. We pick a mix of types and prices so there is a good option for most needs.
How the score works
- Weighted rating. We add 300 average (4.0★) ratings to every product before averaging. This stops a product with only a handful of five-star reviews from beating one with thousands of slightly lower ratings.
- Quality (75% of the score). The weighted rating, measured from 3.5★ (lowest) to 5★ (highest).
- Popularity (25% of the score). How many customers rated it. More ratings means more people have bought and lived with it. This is on a log scale, so 100,000 ratings counts as full marks.
- Final score = 6 + 4 × (quality and popularity combined), rounded to one decimal place. Products are listed from highest score to lowest.
What the labels mean
- Exceptional: 9.0 and above
- Excellent: 8.5 to 8.9
- Very good: 8.0 to 8.4
- Good: below 8.0
Badges
The #1 product on each list is marked Highest Rated. Other badges, like "Best Budget" or "Best Robot", are our editorial picks for a specific need and don't change the score or the order.
Keeping it current
Ratings and purchase counts are copied from Amazon.ca and dated on each page. Prices change constantly, so we don't show them. Click Check Price to see the current price on Amazon.ca.
