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.

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.

Pears are high-acid — no added lemon juice needed

Here is the one thing that surprises people who’ve canned peaches or tomatoes: pears do not need added lemon juice for safety.

• Peaches and tomatoes sit right on the pH 4.6 line, so tested recipes add bottled lemon juice to guarantee safe acidity.
• Pears are reliably more acidic (below 4.6), so water-bath canning is safe without any added acid.

You will dip the cut pears in an ascorbic-acid or lemon-water bath — but that’s only to stop them browning, not for safety. Keep the two ideas separate: acid-for-colour on pears, acid-for-safety on peaches and tomatoes. Follow your Bernardin recipe exactly as written.

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.

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 1.25 cm (½ inch) headspace.
3. Run the headspace tool down the side to release air bubbles; top up syrup to keep 1.25 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 sea level — verify against your Bernardin edition and adjust for altitude.
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 12–24 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 is above sea level, so the boil-time increases with altitude:

Altitude	Add to processing time
0 – 300 m	none (base time)
301 – 900 m	+5 minutes
901 – 1,800 m	+10 minutes
1,801+ m	+15 minutes

Calgary (~1,045 m) and Banff (~1,383 m) need the longer boil. See the full Canadian-city altitude table for the exact band and cross-referenced feet.

Storage and serving

• Cool, dark, dry place at room temperature
• Best quality 12–18 months; safe beyond if the seal holds
• 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; safe if the seal is good.
• Jar didn’t seal. The 24-hour rule.
