Dominion jars are already collector favorites, but this wide mouth square pint version stands out even more. With bold embossed text reading Dominion Mason Wide Mouth – Made in Canada, this jar earns its nickname “Slanty Mason” thanks to the unique italicized “Mason” script — a playful departure from the more standard block lettering found on other Dominion jars.

The square base isn’t just visually striking — it’s also incredibly functional. Originally designed for better shelf efficiency, square jars store beautifully in tight spaces and don’t roll around in drawers or baskets. At just under 4 inches tall, it’s a squat and sturdy little number that holds about 17oz (500ml).

Made in Canada, this jar is a great choice for storing pantry staples, styling shelves, or pairing with one of our wide mouth lids to turn it into a tumbler, gift jar, or countertop storage hero.

Please note:

This listing is for the jar only. Wide mouth lids are sold separately [link to lids].
Expect small vintage quirks like minor bubbles, slight waviness, or light wear — no major chips or cracks.
Part of our authentic vintage collection — no reproductions here.

This is a must-have if you love Canadian glass, square jars, or simply want something a little out of the ordinary.

This jar will fit any Wide Mouth Lid or Accessory.

Approximate dimensions:

Height -3 3/4 inches high without the lid.

Diameter -3 5/8 inches in diameter at the widest point.

Volume -500ml / 17 oz to the neck of the jar.

Each jar is inspected and guaranteed free of cracks and rust. Due to their vintage nature, embossing depth may vary slightly.

'Flea bites', tiny chips in the rim, threding, neck or embossing of the jar are considered normal for a vintage jar and may be present as long as they don't hinder the safe use of the jar.

This listing is for one jar. Lids sold separately – choose your perfect match from our wide mouth jar lids collection.

Meet the Maker

Hi, I’m Marie, the heart (and muscle) behind Mason Jar Merchant. For me, mason jars are so much more than containers! A gift of beautiful vintage jars from my husband’s grandmother sparked a personal love for these versatile jars that quickly grew into a passion and I love sharing their possibilities with others.

As my collection grew, so did my creativity. I began crocheting cozies, painting lids, making custom straw tops, and of course, mason jar tumblers.

Today, Mason Jar Merchant is about more than jars—it’s about empowering people to live healthier, more sustainable and resilient lives. Every product we offer, from vintage jars to lids, tumblers, and accessories, is chosen with the hope that it inspires you to reduce waste, eliminate plastic, and embrace the simple joy of practical beauty.

Are these jars new or used?

Given the age, we have to assume these jars are used. Some have slight signs of aging, small scratches in the surface, etc.

Retro jar

I use it everyday and think of my grandmother! I love her so much all hers are gone in house fire. So thanks! I love this jar! My grandmother left this world long time ago

Thanks for offering these authentic products! The packaging was great. Thanks for the handwritten note.

Tall 24 oz Bernardin canning jars are great

I am happy to have found your company and your 24 oz jars, as Ball has discontinued making their version. My order of jars arrived well-packaged, and within a reasonable time,all the way from the Great North to the edge of the US, where I live. Now, more than ever, I am happy to support a Canadian business!
