WHAT WE DO

We provide pollen forecasts to help you and those you love manage environmental allergies. Aerobiology Research Laboratories analyzes pollen and spore samples to create forecasts for allergy sufferers as seen on the Weather Network, Johnson and Johnson and now through our new personalized subscription program providing you with the exact info you want and need to improve your quality of life. HOW WE DO IT

Aerobiology Research Laboratories (ARL) gathers pollen and spore samples daily using the innovative ARL aeroallergen rotation impaction samplers from 30 monitoring stations across Canada. Samples are collected by associates in the field and shipped to Aerobiology Research Laboratories, where they are analyzed by our highly trained laboratory staff. WHY WE DO IT

Over 9 million Canadians suffer from seasonal allergies and close to 1 million pets (mainly dogs). The counts, or total number of particles per cubic meter of air sampled for each identified particle type, are stored in an ever-growing data warehouse. This database allows us to query and summarize current and historical allergen levels in a flexible and efficient manner, supporting our research and forecasting operations as well as the data needs of our clients. WHY IT MATTERS

This data provides valuable information in development of medications, education and knowing the forecast for pollen levels can help you regulate outdoor activities allowing you to have more control over your quality of life. You can see the pollen forecast on The Weather Network, Johnson and Johnson and now you can get a personalized daily pollen forecast with our subscription program.

🤧 Ever wonder why ragweed allergies are so brutal today?

The answer might be buried at the bottom of a small lake in Ontario.

Scientists studying the annual sediment layers (called varves) preserved at Crawford Lake discovered a dramatic surge in ragweed pollen during the 1800s, right as forests across southern Ontario were being cleared for settlement and agriculture. As trees disappeared, the newly disturbed, open ground created ideal conditions for ragweed to thrive.

What makes Crawford Lake so remarkable is that its unique sediments preserve these changes year by year, almost like the rings of a tree. Those layers tell an incredible story of human influence, from early Indigenous agriculture and European settlement to modern environmental change.

For those of us who study airborne pollen, it’s a fascinating reminder that today’s allergy seasons are shaped not only by the weather, but also by decisions people made centuries ago.

When you and your sibling both have allergies, it turns into a suffering competition. 🏆

“You’re suffering? I’m suffering worse.”.. Bro, I have the receipts - symptoms, medications, all of it. 📈

Download the Allergy Sufferers app and start tracking today, so you’re ready when the suffering competition starts. -> link in bio.

🚨 Ragweed season is officially underway.

Ragweed pollen is beginning to show up across much of Canada, and levels can rise surprisingly fast over the coming weeks.

If you live in Montreal, Quebec City, southern Ontario, or anywhere across southern Canada, now is the time to start checking your local pollen forecast.

The best way to stay ahead of your allergies is to know when pollen levels are expected to increase, not after your symptoms have already started.

📲 Open the Allergy Sufferers App to see the latest forecast for your city and get ready before ragweed peaks.

Does rain actually help allergies? 🤔

The answer is yes... and no.

Rain often provides temporary relief by washing pollen out of the air. But once conditions dry, pollen can return.

At the same time, all that moisture creates ideal conditions for mold growth, and mold spores can become a major trigger for allergy symptoms.

If your allergies don’t improve after a rainy day, mold spores may be the reason.

🌧️ Have you noticed your allergies getting better or worse after it rains? Let us know in the comments!

The first ragweed pollen is now being detected across Kingston, the GTA, and the Montreal area.

If you’ve suddenly developed itchy eyes, sneezing, congestion, or that “am I getting sick?” feeling, it may be ragweed, not a cold.

🌿 This is typically the very beginning of ragweed season, and levels can rise quickly over the next few weeks.

📍 Not in Kingston, Montreal, or Toronto? Ragweed does not start at the same time in every Canadian city.
Open the Allergy Sufferers app to check when ragweed is expected to begin in your area and track daily pollen conditions where you live.

👇 Comment your city and tell me your worst allergy symptom right now. Are you already feeling the start of ragweed season?

The Allergy Sufferers app says pollen is LOW, so why do I still feel terrible?” 🤧

This is exactly what we’re seeing across Ontario right now.

Here’s the surprising reason:

🌡️ Extreme heat can actually reduce grass pollen. Grass produces the most pollen when temperatures are roughly 18–28°C. When temperatures stay well above that range for several days, pollen production can drop sharply, and in some cases the available pollen supply is temporarily exhausted.

That’s why grass pollen levels are currently very low across much of Ontario.

But there’s a second part of the story…

🌧️ Rain + humidity = mold explosion. The same wet conditions that help lawns look green are also ideal for fungal and mold spore growth.

So if:

the pollen forecast is low
you’re still sneezing
your eyes are itchy
your chest feels tight
symptoms are worse after rain

…a mold/spore allergy may be the culprit rather than pollen.

👇Quick Ontario allergy check:
What city are you in, and are your symptoms:
😌 Better
😐 The same
🤧 Worse

We’re already seeing very different experiences between cities.

That bright yellow plant may be getting blamed for the wrong crime. 🌼

Goldenrod is often accused of causing late-summer allergy symptoms because it blooms at the same time as ragweed.

But goldenrod pollen is heavy and sticky, so it is usually carried by insects.

Ragweed pollen is much lighter, travels through the air, and is far more likely to end up in your nose, eyes, and lungs.

So when symptoms suddenly spike, the plant you can easily see may not be the real problem.

Check the Allergy Sufferers app to see what is actually in the air near you.

Save this post for ragweed season and share it with someone who always blames goldenrod.

Did you know goldenrod was often falsely accused?
