How to Can Pears in Syrup in Canada (Bernardin Method)

Home-canned pears are one of the gentlest, most rewarding preserves a new canner can make — soft halves in a light syrup, sweet and floral, nothing like the flat supermarket version. Bartletts come off the Niagara and Okanagan trees from late August into September, and a boiling-water bath is all you need (growing pears in Canada).

This guide covers the Bernardin water-bath method. The processing times below are the standard Bernardin times; verify against your edition and altitude band before you start.

Corrected 31 Aug 2026: the process times, headspace and hot-pack on this page all check out against Bernardin’s Pears recipe — unlike peaches, this one really is a plain syrup pack they publish. Four things were wrong anyway. The spoken summary gave a headspace a quarter-centimetre larger than the method’s own 1 cm, which is also Bernardin’s figure; both now say 1 cm. The times were labelled “at sea level”; Bernardin’s base band runs to 305 m. The page asserted a pH figure for peaches and tomatoes that we retired from the peaches page the same day. And the acid section hedged where it can now be positive: Bernardin’s pears recipe contains no added acid at all. Nothing about the method changed.

Two different jobs acid can be doing

Here is the thing that trips people up after canning peaches or tomatoes: the acid in a pear recipe may not be doing the same job it does in those.

• In some recipes, tested formulations add bottled lemon juice to bring the finished jar into the acid range the boiling-water bath requires. That is a safety step, and where a recipe prints it you add the full amount.
• On pears, the ascorbic-acid or lemon-water bath you dip the cut fruit into is there to stop it browning. That one is cosmetic — it does nothing for shelf safety.

Worth knowing, because the two get conflated and a reader who thinks the dip is protecting them may skip something that actually is.

Bernardin’s own pears recipe adds no acid at all. Not lemon juice, not citric acid — the only acid on their page is the Fruit-Fresh holding bath, and they list it for colour. That is a fact about their recipe, not a rule you can derive from the fruit: if a different tested recipe specifies bottled lemon juice, add the full amount printed. Both jobs can appear in the same recipe.

Ripen off the tree

Pears are the odd fruit that ripen from the inside out and turn mealy and gritty at the core if left on the tree. Growers pick them mature but firm; you finish them on the counter.

• A pear is ready to can when the neck (just below the stem) yields to gentle thumb pressure. If the body is soft, it’s already overripe and will can to mush.
• Ripen a few days at room temperature; speed it up in a paper bag with an apple.
• Can them the day they reach that neck-give stage.

Pick your pears

• Bartlett — the classic Canadian canning pear: softens evenly, holds its shape, traditional flavour. First choice.
• Bosc, Anjou — can be canned but stay firmer and slightly grainier.
• Avoid bruised or overripe fruit — it collapses during processing.

Bernardin’s syrup chart, beside ours

Bernardin publishes three syrup strengths for pears, per canner load of 7 × 1 L jars, plus the fact that you do not have to use syrup at all:

Syrup	Water	Sugar	Sugar by volume
Bernardin very light	10.5 cups (2625 mL)	1.25 cups (300 mL)	~11%
Bernardin light	9 cups (2250 mL)	2.25 cups (550 mL)	~20%
Bernardin medium	8.25 cups (2050 mL)	3.75 cups (925 mL)	~31%
Ours, below	5 cups	3.25 cups (650 g)	~39%

Read that last row honestly: the syrup in this article is sweeter than anything Bernardin calls medium. It is closer to a heavy syrup by their scale. Ours works and tastes good, but if you want their medium, use their numbers. Syrup strength is flavour, not preservation — which is why they publish a very light option and permit no syrup at all.

Three packing media, all permitted by Bernardin: sugar syrup, plain water, or unsweetened fruit juice — apple or white grape. The juice pack is the one this page used to leave out; it is a genuine option for sugar-restricted diets and it tastes better than water. Whichever you use, the process times below are unchanged.

Bernardin also gives about 5 cups (1250 mL) of liquid for 7 × 500 mL jars, and about 17.5 lb (8 kg) of pears per canner load of 7 × 1 L.

What you need

For about 6 × 1 L jars:

• 3 kg firm-ripe Bartlett pears — ripened off the tree
• Ascorbic acid (Fruit-Fresh) or bottled lemon juice — for the anti-browning holding bath (colour only)
• Medium syrup: 3.25 cups (650 g) sugar + 5 cups water (~7 cups syrup)
• Bernardin 500 mL or 1 L jars
• Fresh SNAP lids and bands
• Water-bath canner (see the water-bath canner buying guide)
• Standard canning kit — jar lifter, funnel, headspace tool; a melon baller for coring

Method

Step 1: Syrup and holding bath

1. Combine sugar and water; bring to a simmer; keep hot.
2. Prepare the water-bath canner; warm the jars.
3. Mix the anti-browning holding bath — ascorbic acid (per its package) or a few tablespoons of bottled lemon juice in a bowl of water.

Step 2: Peel, halve, core

1. Peel the pears.
2. Halve lengthwise and core — a melon baller scoops the seed cavity cleanly; trim the fibrous line to the stem.
3. Drop each half into the holding bath as you work, to keep them pale.

Step 3: Heat in syrup (hot pack)

1. Drain the pears from the holding bath.
2. Add them to the simmering syrup and heat 4–5 minutes until warmed through. Hot-packing reduces siphoning and stops the fruit floating in the jar.

Step 4: Pack

1. Hot-pack the pear halves cavity-side down, layered, into each hot jar.
2. Pour hot syrup over to cover, leaving 1 cm (½ inch) headspace.
3. Run the headspace tool down the side to release air bubbles; top up syrup to keep 1 cm.
4. Wipe rims with a clean damp cloth; apply fresh SNAP lids fingertip-tight.

Step 5: Process

1. Lower jars into the boiling-water canner; water must cover the lids by 2.5–5 cm.
2. Return to a full rolling boil, then start the timer:
   • 1 L jars: 25 minutes
   • 500 mL jars: 20 minutes
   • …at altitudes up to 305 m — Bernardin’s base band, not sea level. Adjust upward above that.
3. Keep a steady rolling boil the whole time; top up with boiling water if the level drops.

Step 6: Cool and check

1. Turn off the heat; wait 5 minutes, then lift jars straight up onto a towel.
2. Cool 24 hours undisturbed; don’t retighten bands.
3. Check seals — lid concave and immovable. Label and store.

If a jar didn’t seal: the 24-hour rule — refrigerate and use, or reprocess with a fresh lid.

Altitude adjustments

Most of Canada sits above 305 m, so the boil time goes up with altitude — Bernardin’s bands are in the table at the foot of this page. Calgary (1,084 m) and Banff (~1,383 m) both need the longer boil. See the full Canadian-city altitude table for your town’s exact band.

Storage and serving

• Cool, dark, dry place at room temperature
• Best quality 12 months — Bernardin’s guidance is to use home-canned food within one year. That is a quality window, not an expiry: the jar is as safe as the process made it. Colour, flavour and texture fade.
• After opening: refrigerate, use within 5–7 days
• Inspect before eating — a bulging lid or off smell means discard

Serve over yogurt or oatmeal, in a pear crumble, alongside pork, or straight from the jar. The syrup is excellent in a winter cocktail or drizzled over pancakes.

Common problems

• Pears floated to the top of the jar. Too little hot-pack heating or overripe fruit. Heat in syrup a little longer next time and pack firm-ripe fruit.
• Fruit browned in the jar. The holding-bath step was skipped or too weak. It’s a colour issue, still safe.
• Grainy texture. Bosc/Anjou are naturally grainier than Bartlett, and over-tree-ripened pears go gritty at the core — ripen off the tree.
• Cloudy syrup. Usually starch from very ripe fruit or hard water; and it does not change whether the jar was processed properly.
• Jar didn’t seal. The 24-hour rule.
