Queen Bees, Imports, and Overwintering in Ontario: A Practical 2026 Outlook for Beekeepers

If you keep bees in Ontario, sooner or later you learn that winter does not kill colonies by itself.

Winter exposes every weakness that was already there.

A colony that goes into winter with a poor queen, high mite pressure, a light population, poor stores, or too much moisture is already in trouble before the first hard frost. By the time you find the dead-out in February or March, the failure usually started months earlier.

That is why queen quality matters so much. Not in a vague, sentimental way, but in a very practical way. The queen determines whether the colony can produce enough healthy bees at the right time. Varroa determines whether those bees are physiologically fit enough to survive. Nutrition determines whether the colony has the fuel to maintain itself. Equipment and winter setup determine whether the bees can stay dry, clustered, and in contact with food.

None of these things work alone.

A good queen cannot save a colony that is full of mites. A low mite count will not fix a failing queen. A heavy hive can still die if the cluster is too small or the bees cannot access stores. And wrapping a hive in fall will not repair mistakes made in August.

For Ontario beekeepers going into 2026, the useful question is not “Should I use imported queens or local queens?” The useful question is:

What queen source gives this colony the best chance to build strong, healthy winter bees under Ontario conditions?

That is where the conversation has to start.

Ontario’s numbers are telling us the same thing every year

Ontario’s official 2025 apiculture winter loss report estimated 37% overwinter mortality for commercial beekeepers during the 2024–2025 winter. That was better than the previous winter’s estimated 50% loss, but it is still a serious number. Small-scale beekeepers were estimated at about 43% overwinter mortality, roughly six percentage points higher than commercial operators.

The reported suspected causes are more useful than the loss number itself. Ontario commercial beekeepers pointed to Varroa mites and associated viruses, climate and weather, weak colonies in fall, poor queens, starvation, and pesticide or environmental chemical exposure as contributing factors. Small-scale beekeepers reported many of the same issues, with weak fall colonies, weather, Varroa, and poor queens all appearing in the mix.

That pattern should shape how people manage bees.

When poor queens, weak fall colonies, Varroa, starvation, and weather keep showing up together, it tells us the problem is not one magic bullet. It is the interaction between queen performance, parasite load, timing, food, and winter biology.

A colony does not need to be perfect to survive winter. But it does need to be viable. It needs enough healthy bees, a queen that built the right population at the right time, low enough mite pressure before winter bees were raised, adequate food, and a setup that manages moisture.

If any one of those pieces is badly wrong, winter will usually find it.

A queen is not “good” because she is alive

This is one of the first hard lessons new beekeepers need to learn.

Finding the queen is not the same as evaluating the queen.

You can have a queen walking around on the comb and still have a colony that is not building properly. She may be old. She may be poorly mated. She may be running out of stored sperm. She may be damaged. She may be laying, but not enough. She may be producing a scattered brood pattern. The colony may be quietly trying to supersede her.

The brood nest tells you more than the queen’s body does.

A productive queen in season should give you a brood pattern that makes biological sense. You want to see eggs, larvae, and capped worker brood in a pattern that matches the time of year and the strength of the colony. You want the colony to build when weather and forage allow. You want the population to be moving in the right direction. You want the hive to feel organized.

A weak queen often shows up as a weak timeline. The colony is always behind. It does not expand when similar colonies expand. It has patchy brood. It has too much drone brood where you need worker brood. It keeps starting queen cells. It has adult bees flying, but not enough young bees coming behind them.

In spring, that costs production. In August, that can cost the colony.

Late summer is where queen judgement becomes serious. The queen is producing the bees that will become part of the winter population. If she is failing then, the hive may not raise enough long-lived winter bees. You can feed that colony. You can wrap that colony. You can worry over that colony. But if the population was not built properly, you are trying to winter a biological deficit.

Imported queens have a place, but they are not a full plan

Imported queens are part of Canadian beekeeping for a reason. Our season does not line up neatly with our demand.

Canadian beekeepers need mated queens early in spring to replace winter losses, requeen problem colonies, make splits, and rebuild operations. Ontario cannot reliably produce large numbers of mated queens early enough to meet that need because queen production depends on drones, mating weather, temperatures, and seasonal development.

Agriculture and Agri-Food Canada notes that imported queens and package bees are used to rapidly replace overwinter queen and colony losses in spring and to grow operations through the season. Queens may be imported only from countries and regions that CFIA has deemed not to pose unacceptable risk to Canada.

University of Guelph reporting states that Canada imports approximately 260,000 to 300,000 queen bees annually from warmer regions such as Hawaii, California, Chile, and New Zealand because domestic production cannot meet demand.

That is the practical reality.

Imported queens are useful when timing matters. If you open a hive in spring and it is queenless, you may not have the luxury of waiting weeks for a locally mated queen. If you are rebuilding after losses, imported queens may be the only way to get colonies moving early enough. For commercial and sideline beekeepers, that timing can matter financially.

But imports are not a complete resilience strategy.

An imported queen has not proven herself in your yard, under your winter, with your forage, your mite pressure, your management, and your local climate. That does not mean she is bad. Some imported queens perform very well. It means you need to treat her as an unknown until your own records prove otherwise.

A practical beekeeper does not argue from ideology. A practical beekeeper tracks performance.

If you use imported queens, record the source, installation date, acceptance, brood pattern, temperament, buildup, mite levels, honey production, fall strength, and winter survival. After a few seasons, you will know which suppliers and lines work in your conditions. Without records, you are just repeating opinions from other bee yards.

Local queens are valuable when they are selected, not merely local

Ontario-raised queens can be excellent. They can also be ordinary.

The value of a local queen is not that she was produced within a provincial border. The value is that she may come from stock selected under local pressure: winter, spring buildup, temperament, forage rhythm, mite pressure, brood health, and beekeeper handling.

That distinction matters.

A queen raised from a colony that overwintered well, built cleanly in spring, held a good brood pattern, stayed workable, and maintained strength has more practical value than a queen raised simply because larvae were available.

For Ontario beekeepers, the right questions to ask a queen or nuc supplier are direct:

Was the queen imported, Ontario-raised, or overwintered?

If she was Ontario-raised, was she mated here?

Was the mother colony selected for winter survival?

What traits are you selecting for: temperament, honey production, hygienic behaviour, overwintering, spring buildup, lower mite growth?

Is the nuc overwintered or spring-made?

What permit covers the sale?

What happens if the queen fails shortly after pickup?

Those are not rude questions. They are normal livestock questions.

If someone is selling living colonies, queen source matters. Brood condition matters. Disease status matters. Permit status matters. A cheap nuc with a poor queen is not cheap after you spend the rest of the season trying to fix it.

Overwintered nucs are often useful, but they are not magic

An overwintered nuc can be one of the best tools available to an Ontario beekeeper.

The reason is simple: the queen and bees have already come through winter as a functioning unit. That gives you information you do not get from a newly made spring nuc. A good overwintered nuc shows that the queen could maintain a colony through local winter conditions, restart brood rearing, and build again in spring.

That is valuable.

But “overwintered” is not a guarantee of quality. A nuc can survive winter and still come out weak. The queen may be aging. The brood pattern may be poor. The population may be thin. The colony may be hungry. There may be disease or high mites. It still needs to be inspected and managed like any other colony.

A strong overwintered nuc should show bees covering the brood, a laying queen, brood in multiple stages, enough food for current conditions, no obvious brood disease, and a population that is expanding rather than merely surviving.

The danger is treating overwintered nucs as a shortcut. They are not. They are a head start when they are well produced and well managed.

For a new beekeeper, a quality overwintered nuc from a reputable Ontario producer can be a better learning unit than a weak package or a poorly made nuc. But the beekeeper still has to monitor mites, feed when needed, evaluate the queen, and build the colony for winter.

Banked queens are a different subject

This needs to be kept separate.

An overwintered nuc queen is a queen that survived winter while heading a small colony.

A banked queen is a queen held in a queen bank, usually in a specialized system where queens are maintained without each queen running her own normal colony.

Those are not the same thing.

Recent research on overwintered queen banking is interesting because Canada is looking for ways to reduce dependence on spring imports. A 2025 Journal of Economic Entomology study compared overwintered banked queens with newly imported mated queens. The study found queen survival in overwintered queen banks was low, at 15% overall, and sperm viability declined after overwintering in banks. However, the queens that survived and were introduced into colonies performed comparably to imported queens in introduction success, colony size, honey yield, and winter survival.

That result is not an argument against overwintered nucs. It is not proof that local queens are weak. It tells us queen banking is technically difficult and still developing.

For most small-scale Ontario beekeepers, queen banking is not the practical first move. The practical first move is to overwinter strong colonies, buy better nucs, learn queen evaluation, control mites earlier, and keep better records.

The real winter plan starts in August

By the time you are wrapping hives, most of the important winter work has already been done or missed.

The bees that carry the colony through winter are raised in late summer and fall. They need to be healthy. That means the queen must be producing properly, the colony must have enough nutrition, and mite pressure must be low enough before those bees are raised.

This is where many colonies fail.

A beekeeper treats late. The mites drop. The beekeeper feels better. But the damage was already done to the winter bees.

That is why mite timing matters more than people want to admit. A colony can look strong during goldenrod and still be raising damaged winter bees if Varroa and associated viruses are high. The entrance can be busy. The hive can feel heavy. The colony can still be in trouble.

The practical Ontario rhythm should look something like this:

In spring, confirm survival, food, queenright status, and buildup. Do not make splits from weak colonies just because the calendar says it is split season.

In late spring and early summer, identify your best colonies. Watch brood pattern, temperament, buildup, and swarm tendency. These are the colonies you learn from.

In summer, monitor mites properly. Do not guess. Do not rely on whether the bees “look good.”

After honey harvest, or before the winter-bee production window, make sure mites are controlled early enough to protect the bees that need to live through winter.

In August, judge queens seriously. A colony with a failing queen in August is not a wait-and-see project. It is a winter-risk colony.

In early fall, check weight and feed while bees can still take syrup down properly.

Before winter, decide which colonies are actually worth wintering. Combining two weak colonies can be better beekeeping than losing both separately.

Wintering is not about saving every box. It is about wintering viable colonies.

Weak colonies should not be carried out of guilt

This is one of the harder habits to learn.

New beekeepers often want to save every colony. That instinct is understandable, but it can lead to poor decisions. A weak colony can become a dead-out, a robbing target, a wax moth mess, or a source of mites and disease pressure for the rest of the yard.

Before winter, ask hard questions.

Is this queen good enough?

Is the brood pattern strong enough?

Is the colony building or shrinking?

Is there enough population to form a winter cluster?

Are mite levels actually under control?

Is there enough food, and is it positioned where bees can use it?

Is there disease?

Would this colony be stronger if combined with another?

A good beekeeper is not the person who refuses to give up on a hopeless colony. A good beekeeper is the person who makes the decision early enough to protect the bees that can still be protected.

Sometimes that means requeening. Sometimes it means combining. Sometimes it means using the resources to strengthen a better colony. Sometimes it means accepting that the unit is not winter-worthy.

That is not failure. That is management.

What I would tell a new Ontario beekeeper buying bees in 2026

Do not start by asking, “How much honey will I get?”

Start with these questions:

Where is the queen from?

Is this a spring-made nuc or an overwintered nuc?

What does the brood pattern look like?

Are there eggs, larvae, and capped worker brood?

How many frames are actually covered with bees?

Are there enough stores for current conditions?

Has the colony been inspected for disease?

What is the mite-management history?

Is the supplier permitted?

What support do they provide if the queen is not accepted or fails immediately?

Then, once the bees are in your yard, keep records from the first inspection. Record queen source, brood pattern, food, population, temperament, mite counts, feeding, treatments, and winter outcome.

Your records are how you become a better beekeeper. Without records, every year feels like a surprise. With records, patterns start to show.

You may learn that one supplier’s queens build better in your yard. You may learn that certain colonies always carry higher mites. You may learn that your fall feeding is too late. You may learn that your strongest-looking September colonies are not always your best March survivors. You may learn that you are taking too much honey from first-year colonies.

That is how experience becomes useful.

The best queen source is the one that performs in your management system

There is no honest article that can tell every Ontario beekeeper to use only imported queens, only local queens, only overwintered nucs, or only home-raised stock.

The truth is more practical.

Imported queens are important because they fill the early spring supply gap.

Ontario-raised queens are important because local selection can improve resilience.

Overwintered nucs are important because they provide early-season colonies that have already survived local winter conditions.

Queen banking is important research, but it is not yet a simple answer for most beekeepers.

The right approach is to use the tool that fits the situation, then measure the result.

If an imported queen saves a valuable spring colony, use her. If an overwintered nuc from a local producer consistently builds well and survives, buy from that producer again. If your own survivor colonies show good temperament, low mite growth, and strong wintering, consider raising from them. If a supplier’s queens repeatedly fail in your yard, stop buying from that supplier.

That is not complicated. It is just disciplined.

Bottom line

Ontario beekeeping in 2026 will reward beekeepers who make decisions before problems become visible from the outside.

Judge queens by brood and colony trajectory, not by whether you happened to see her.

Control Varroa before winter bees are damaged, not after the colony starts to collapse.

Buy queens and nucs from people who can explain their stock, not just people who have early availability.

Treat imported queens as useful spring tools, not as a complete long-term genetics plan.

Value overwintered nucs when they are strong, inspected, and produced by reputable local beekeepers.

Do not confuse queen banking research with ordinary overwintered nucs; they are different systems.

Do not carry weak colonies into winter just because you feel bad combining them.

The queen is the colony’s future, but she is not working alone. Her success depends on the beekeeper giving the colony the conditions to turn her laying pattern into healthy bees, healthy bees into a winter cluster, and a winter cluster into a colony that is still alive when spring opens again.

That is the work.

Not buying bees. Not hoping. Not wrapping boxes and crossing your fingers.

Real beekeeping in Ontario is reading the colony early enough to act while action still matters.
