About our best-before dates

We work hard to bring proper British groceries to Canada, but importing food across an ocean is not as tidy as stocking a supermarket shelf down the road.

Some products arrive with long dates. Some arrive with shorter ones. Different products come through the import process with different shelf lives, so the dates are not always as neat or predictable as they would be in a regular Canadian supermarket.

Most online grocery shops do not show best-before dates unless something is getting close. We do it differently.

If you were shopping in our Halifax store, you could pick up the product, turn it over, and check the date before buying. We think our online customers should get that same level of transparency.

That is why we show best-before dates clearly on our products.

What "best before" actually means

A best-before date is about quality — flavour, texture, freshness, and how the product is expected to be at its best.

It is not the same as a "use by" or expiry date, which only appears on certain regulated foods.

For everyday groceries like chocolate, biscuits, crisps, sweets, tea, sauces, jams, and pantry items, the best-before date is a quality marker, not a safety marker.

Why our dates vary so much

British imports are unpredictable. We do not get to choose every date that arrives in Canada, and different products naturally come with different shelf lives.

A jar of sauce may have months or years on it. A bag of crisps might arrive with a much shorter window and still be completely normal for that type of product.

We check dates, show them clearly, and give you the information before you buy — because that is how it should be.

What the colours mean

  • More than 30 days remaining
  • Within 30 days
  • Within 5 days, or past the best-before date

The product page will still show the actual date, so you can decide what works for you.

Why some customers like shorter dates

Many of our regular customers deliberately shop shorter-dated items when the price makes sense.

A chocolate bar with two weeks left is often every bit as good as one with six months left — and if we can pass on a saving instead of letting perfectly good food go to waste, everyone wins.

It is not about cutting corners. It is about being clear, fair, and sensible with stock that has travelled a long way to get here.

Frequently asked questions about Princes Tuna & Mayonnaise Paste

Q: What does Princes Tuna & Mayonnaise Paste taste like?

A: It is a creamy, savoury paste with a mild tuna flavour rounded out by mayonnaise and a gentle hint of mustard and lemon juice. The texture is smooth enough to spread straight from the jar, making it the sort of thing that turns two slices of bread into a proper lunch without much effort. It is not sharp or heavy, just quietly satisfying in the way a good sandwich filling should be.

Q: Does Princes Tuna & Mayonnaise Paste contain dairy?

A: Princes Tuna & Mayonnaise Paste is dairy-free. The mayonnaise in the recipe is made with rapeseed oil and pasteurised egg yolk rather than any dairy ingredient, so there is no milk in the product. It does, however, contain fish, eggs, wheat, mustard and soya, so those with allergies to any of those should take note before spreading.

Q: What can you use Princes Tuna & Mayonnaise Paste for beyond sandwiches?

A: Sandwiches are the obvious answer, but the paste also works well on crackers, stirred through a quick pasta salad, or spread onto toast as a fast savoury snack. The 75g jar is a handy single-use size, so there is no half-finished pot lingering in the fridge. For British expats in Canada, it is the kind of pantry staple that fills a very specific gap when you want something quick and familiar without making it from scratch.

More about Princes Tuna & Mayonnaise Paste

Princes Tuna & Mayonnaise Paste sits in a well-established corner of the British pantry: the sandwich paste. These small jars and tubes of ready-to-spread filling have been a staple of British lunches for generations, sitting alongside fish paste, beef paste and the rest of a category that Canada never quite replicated in the same way. The 75g size is a single-serve-friendly format, enough for a few rounds of sandwiches without committing to a large tin.

For British expats and anyone who grew up with paste sandwiches wrapped in cling film, finding Princes Tuna & Mayonnaise Paste in Canada is not always straightforward. It is the kind of product people search for specifically, not because nothing else spreads on bread, but because this is the version they remember.

The jar stores easily in a cool, dry cupboard until opened, then needs refrigerating and using within three days. At 75g it does not hang around long anyway. It is confirmed dairy-free, which is a useful detail for anyone navigating that.

Princes produces a range of fish-based pastes and canned seafood products, and the paste sits naturally alongside the broader Princes in Canada range available here. If you are putting together a British cupboard more generally, the British pantry favourites collection is worth a look.

The paste ships from within Canada, so whether you are in Edmonton or Guelph, it arrives without the delays and customs uncertainty of an overseas parcel. Small jar, long shelf life before opening, zero fuss.

What our customers say

4.9 from 427 Google Reviews
I work close-by in Bayer’s Lake and love to pop in for a healthy and delicious lunch when I don’t bring one from home! I’ve had over 10 flavours of the pies, and tried almost every sweet they make. I adore this place, from the amazing food, to the nostalgic candies and British goods they carry, and especially the wonderful staff who always greet me by name and ask how Im doing every time I come in. My Papa was born and raised in England and loved to share tastes of home with his whole family, I wish he was able to see this place, he would’ve been delighted ❤️❤️❤️

The story of Princes Tuna & Mayonnaise Paste

A Small Jar With a Very British Job

Princes Tuna & Mayonnaise Paste is not trying to be grand. It is a 75g jar of sandwich filling, the sort of thing that belongs in the cupboard for toast, crackers, quick lunches and those moments when making a proper meal feels like a bit much. British shoppers know this category well: fish paste, meat paste, sandwich paste, all lined up in small jars with the quiet confidence of something that has been solving tea-time problems for generations.

Read the full story

Not A Product-Origin Tale, But A Brand One

There is no firmly sourced product-level origin story for this particular tuna and mayonnaise paste, so it would be daft to pretend there is a dramatic founding moment involving one heroic sandwich. What we can say is that the modern jar sits within the wider Princes world of canned fish, pantry goods and sandwich fillings. That matters, because the brand name on the label carries a long history in British cupboards, even when the individual jar’s own paper trail is more modest.

The Princes Name And The Tinned Fish Thread

Princes traces its roots to 1880, when William Muirhead Simpson and Canadian Frank Roberts founded a partnership that began by importing tinned lobster from Canada. The business traded as Simpson Roberts before creating several brands, with the Princes name introduced in 1900. Its early life was closely tied to canned fish, which makes a tuna-based paste feel very much at home in the family, even if this exact jar arrived later in the story.

The Corporate Bit, Kept To A Sensible Amount

In 1973, the combined business was sold to Italy’s Buitoni group; Buitoni was later acquired by Nestlé in 1988, and Princes was then sold to Mitsubishi Corporation in 1989. By 2013, the company was described as the UK’s largest supplier of tinned food. In 2011, Princes also acquired two East Anglian canning operations, along with the Crosse & Blackwell and Farrow’s brands from Premier Foods. That is quite a lot of boardroom shuffling for a little jar of paste, but it helps explain how Princes became such a familiar name across many British pantry shelves.

Liverpool, Canada, And A Neat Little Circle

The company has long been associated with Liverpool, a city whose port made it a natural place for importing and distributing canned goods in the Victorian era. There is also a pleasing Canadian connection in the brand’s earliest trade, since the original partnership imported tinned lobster from Canada. For British expats now buying a Princes jar back in Canada, that is a tidy loop. Grocery history does enjoy the occasional joke, even if it takes more than a century to land.

Why This Jar Still Makes Sense

Tuna and mayonnaise paste belongs to a very particular British cupboard logic. It is useful, familiar and faintly nostalgic, especially for anyone who remembers small jars turning up beside sliced white bread, packed lunches, caravan holidays or a grandparent’s kitchen shelf where everything had its place. It is not glamorous, which is rather the point. It spreads, it fills a gap, and it tastes like the kind of practical British food people miss more than they expected. For shoppers in Canada looking for that exact little jar-shaped memory, The Great British Shop is a quiet sign-off from home.
