Amazon and Walmart are the two carts many Canadians open without thinking. That habit is expensive if you treat their cashback the same way. Amazon vs Walmart cashback Canada is not a permanent ranking. It is a same-day comparison of item price, eligible categories, marketplace rules, grocery exclusions, and which portal actually lists the store.

This is not a claim that Walmart always pays more, or that Amazon never does. Portal rates rotate. Amazon cashback is often category-specific. Walmart listings can show a higher "up to" figure that does not apply to the whole basket. The useful question is which store wins this order, on this portal, today.

Use Canada Cashback Monitor to compare live offers, then confirm the terms on the portal before you click. Shop-now links on this site go through stored affiliate URLs, so the destination stays current.

Quick answer: Amazon or Walmart for cashback?

Neither store is always the cashback winner.

A practical decision order is:

Find the same item (or a true equivalent) on Amazon and Walmart.
Check who sells it: the retailer itself, or a third-party marketplace seller.
Compare the delivered total after shipping, taxes, and membership perks you already pay for.
Open the current portal listings and read category, grocery, gift-card, and marketplace exclusions.
Start a fresh shopping trip through one portal. Do not bounce between sites after the click.

Choose Amazon when the item is cheaper there after Prime shipping, the category is listed as eligible, and you follow the empty-cart rule. Choose Walmart when the delivered price is better, pickup is easier, or a portal is paying on the categories you are actually buying. Cashback should break a close tie. It should not justify a more expensive basket.

Same cart size. Two different reward machines.

Amazon is a marketplace first. Sold-by-Amazon items, Amazon devices, grocery, books, and third-party seller listings can all sit in one checkout. Cashback portals rarely treat that cart as one rate. A fashion or home category might pay while electronics, gift cards, or marketplace items pay nothing.

Walmart is a full-line retailer with a growing marketplace of its own: groceries, household staples, electronics, clothing, and pickup. More Canadian portals list Walmart on a typical week than list Amazon. That coverage gap matters. A modest Walmart rebate you can actually claim can beat an Amazon headline that excludes your category.

Shop Amazon through a stored portal link such as Amazon via Rakuten. Shop Walmart the same way: Walmart via Rakuten, Walmart via TopCashback, or Walmart via Great Canadian Rebates. Those links resolve from the live store database rather than a hardcoded affiliate URL.

What actually differs for Canadian shoppers

1. Portal coverage

Walmart usually appears on more cashback and rewards sites: Rakuten Canada, TopCashback, Great Canadian Rebates, CAA Rewards, and sometimes Swagbucks. Amazon is thinner. On many weeks the cash offer is a modest "up to" rate on one or two portals, with points programs listed separately.

Before you decide:

Open Amazon and Walmart and count the portals that currently show a shoppable offer.
Ignore points unless you will redeem them.
Treat "up to" as a ceiling, not the rate on groceries or a mixed cart.

A higher Walmart headline is useless if your items are in an excluded category. A lower Amazon rate is still useful if Amazon is cheaper by more than the rebate.

2. Category rates, not store-wide rates

Amazon cashback in Canada is famous for the category trap. Portals often pay on listed departments only. If you buy a laptop on a week when fashion is the featured category, you can earn nothing. Gift cards, many electronics, and third-party marketplace orders are common exclusions.

Walmart has the same "up to" problem in a different shape. A portal may advertise a high ceiling for specific departments while groceries, marketplace sellers, gift cards, or in-store pickup pay a lower rate or zero. Read the breakdown on the portal store page, not the number on a comparison tile.

Do not assume last week's rate still applies. Compare immediately before checkout.

3. Marketplace, grocery, and how you pay

Both sites mix first-party inventory with third-party sellers. Cashback is often limited to the retailer itself. If the offer says sold and shipped by Amazon or Walmart, a marketplace seller in the same cart can dilute or void the reward.

Grocery is another split. Amazon grocery and Walmart grocery are convenient, but portals frequently exclude groceries, delivery fees, and pickup orders. If dinner is the cart, confirm grocery eligibility before you click.

Gift cards, taxes, shipping, and tips usually do not earn. Unapproved coupon codes can void tracking. If you already have a store promo, check whether the portal allows it.

4. Prime, Walmart+, shipping, and returns

Membership value is not cashback, but it changes the math.

Amazon Prime can erase shipping on eligible items. That is often worth more than a 1% portal rebate on a small order.
Walmart may be cheaper on the shelf, offer cheaper or free shipping thresholds, or let you pick up the same day. Pickup can be excluded from cashback even when the item price is better.

Returns matter. A rebate on an item you send back is not a rebate. Compare return windows and whether the seller is the retailer or a marketplace third party.

If the all-in delivered price already differs by $20 and cashback is a few dollars, the cheaper store wins. Do the math on the actual cart.

Tracking: Amazon is picky

Amazon tracking is stricter than most Canadian retailers.

Start with an empty cart. Add items after the portal click, not before.
Complete checkout in the same browser session.
Avoid coupon extensions and extra click-throughs after the portal.
Keep the order confirmation until the reward is approved.

Walmart is usually simpler, but pickup, app-only orders, and marketplace mixed carts still fail. One portal per order. Do not open both stores from the same click.

Pending times differ. Rakuten, Great Canadian Rebates, TopCashback, and CAA Rewards do not share one calendar. Read the merchant terms on the portal you used.

Stack the rebate. Do not double-count it.

Cashback is one layer:

Store price and shipping.
Portal rebate or points on eligible categories.
Credit-card rewards on the payment.

A strong card on a slightly more expensive cart can still lose. Compare net cost. For the stacking playbook, use How Cashback Stacking Works in Canada.

Checklist before you checkout

Price the same item on Amazon and Walmart, including shipping.
Note sold-by and shipped-by. Skip marketplace sellers if the portal excludes them.
Open current listings on Amazon and Walmart.
Read category, grocery, gift-card, pickup, and coupon exclusions.
Click once through a stored link such as Amazon via Rakuten or Walmart via Rakuten.
Keep proof until the return window closes and cashback is approved.

Bottom line

There is no permanent winner in Amazon vs Walmart cashback. Amazon wins when the item is cheaper there, the category is eligible, and you start from an empty cart. Walmart wins when more portals list it, the delivered price is better, or the "up to" rate actually covers what is in your basket.

Compare the cart first. Then compare current portal offers. Then click once. For Amazon category traps, use the Amazon cashback guide. For more store comparisons, see the rest of the blog.
