There are a number of sites that offer free grocery coupons in Canada, for saving money on your shopping bills.
Here are some of the most popular grocery coupon sites (in alphabetical order):

This is Procter & Gamble’s dedicated grocery coupon site. You can register and get excellent coupons from many famous P&G brands, such as Olay, Pampers, Gillette and more. P&G mail these coupons out to your home.

Couponclick is slightly different to the other sites on this list, in that you print these free grocery coupons yourself. But they do have excellent coupons for the well-known brand names, such as Colgate, Clorox, Palmolive and more.

On Gocoupons, these coupons are mailed out to you, but they may vary depending on what province you live. You will see products you should recognize such as Yoplait and Royale. The selection on this coupon site doesn’t seem to be as big as some of the others on this list, but if they stock coupons for your favorite products, then you might as well take advantage of the discounts.

Save.ca is a really popular coupon site, which mails you selected coupons. Loads of big brands have been seen on here, such as Sensodyne, Herbal Essences, Glade, Tampax and more.
Quite often, they even provide coupons that you can claim a completely free product from your local supermarket, such as the free Mars Bars recently.
A point to note about Save.ca though – only request coupons that you feel you will actually use. If you have ordered coupons and not redeemed them, you run the risk that they will cancel your account and not send you any more free grocery coupons.

On Websaver.ca, you must choose a minimum of 6 free coupons, which they will then mail out to your home. You could see coupons from L’Oreal, Dr Scholl, Garnier and more.
Conclusion
Each of these sites is specifically Canadian, so you don’t have to worry about accidentally getting US coupons, then not being able to use them in-store.
If you practice the arcane art of stock-piling, these types of grocery coupons are invaluable in stocking up your kitchen shelves on a budget.
Remember, there is more to life than grocery coupons. If you check out the printable coupon category here on Bargainmoose, you can see that there are loads of free printable coupons for many more Canadian stores.
