With snow covering most of Toronto, this month has a low pollen count. Allergies in January are most likely mold or pet related. Having trouble distinguishing between hay fever and a winter cold? Check out our guide to find out the differences.
So long as the freezing temperatures continue in Toronto, pollen rarely makes its presence felt this early in the year.
The first month of spring brings with it the beginning of tree pollen season. Trees in season include Cedars, Hazels, Alders, Elms, Maples, Willows, Poplars, Pines and Oaks.
April showers bring… grass pollen?! Welcoming Kentucky grass, the first representative of the upcoming grass pollen season. Toronto’s Mulberry and Walnut trees come to life again this month.
Sycamore trees begin pollenating in May. Kentucky, Bermuda, Johnson, Orchard, and Timothy grasses are spreading their pollen evenly across Toronto.
By June, pines, birch and oaks are the primary producers of tree pollen. Sweet vernal joins the party and adds its pollen to the other grasses.
In July, grass pollen is peaking in Toronto while the majority of tree pollen production is coming to an end for another year.
The good news is that tree pollen production has peaked with the exception of a few late bloomers. Grass pollen is also on its way out. In Toronto, ragweed is now the dominant pollen producer, along with dock, nettle, mugwort and plantain.
Ragweed is on the decline, signaling that hay fever season is finally winding down. Feel free to take a deep breath without causing any runny noses or itchy eyes – and hope that the sun sticks around to make the most of it!
With any luck, the last of the weed pollen is on its way out, although some ragweed along with crab grass may hang around until the first frost of winter in Toronto.
Enjoy the changing leaf colours without your eyes watering: November’s pollen count tends to be low, along with the temperature.
December brings the first official day of winter in Toronto, which means traditionally low levels of pollen for the next few months.

Pollen Levels
The following table shows the risk level for each type of pollen derived by applying NAB guidelines to our data and taking percentile values from the extended season for each type of pollen.
Severity of pollen is dictated by the PPM number, which stands for Pollen Grains Per Cubic Metre. The weather and time of day can also be a big factor when it comes to how the pollen count can affect you. As pollen falls to the ground when the heat dissipates during the evening, this can mean your seasonal allergy symptoms get worse and is why many allergy sufferers have worse symptoms in the night. On rainy days, you’ll find your allergy symptoms are easier to manage as rain tends to wash pollen away.

Ash trees come in a variety of species (45 to 60 species worldwide), but the most common in Canada is white ash. Ash trees can be found just about anywhere. Unfortunately for allergy sufferers, ash trees can produce pollen at almost any time of year depending on the species, but peak primarily in the spring. Ash tree allergy symptoms you might experience include runny nose, coughing, congestion and sneezing. To help avoid some of these symptoms, do your best to stay indoors. If these symptoms become difficult to manage on your own, ask your doctor if allergy medication might be best for you.Peak Season : Spring -
Birch
Birch trees grow in every region of Canada, making them particularly hard to avoid. Birch tree pollen peaks during March to June across Western, Eastern and Atlantic Canada. If you’re allergic to birch tree pollen, you might experience symptoms like sneezing, nasal congestion, wheezing, runny nose and watery eyes. Sign up for pollen alerts in your area, and help manage your allergy symptoms by keeping your windows and doors closed as much as possible.Peak Season : Late Winter to Spring -

Elm trees come from a family of about 35 species. They pollinate mostly in February (sometimes as late as April). However, pollination can still occur at any time of year. If you’re allergic to elm trees, you might endure symptoms like sneezing, nasal congestion, wheezing and itchy throat, nose and eyes. Help prevent allergy symptoms by getting personalized pollen alerts and limiting time outdoors when levels are high. You’ll want to wash your bedding and clothes more often too!Peak Season : Winter and Late Summer -
Pine
Pine Trees can be found growing throughout Canada. Fortunately, pine pollen allergies are fairly uncommon, but people can be severely allergic to pine nuts. Pine pollen allergy symptoms can include itchy eyes, runny nose, congestion and coughing. Pine nut allergy symptoms can be as severe as other nut allergies, including symptoms such as anaphylaxis, tightness in the chest and difficulty breathing. To try to evade pine pollen allergies, get personalized alerts about the pollen count in your area and do your best to stay indoors when pine pollen levels are high.Peak Season : Spring to Early Summer -

You can help manage these symptoms by avoiding peak pollen levels with personalized pollen alerts for your area. Cleaning your house often and doing laundry more frequently can also provide relief, as well.Peak Season : Spring -
Juniper
Juniper trees produce pollen grains about 20 to 30 micrometers in size (making them barely visible to the naked eye), which is small enough to become airborne and impact allergy sufferers from miles and miles away. Symptoms from juniper tree pollen allergies can include congestion, sneezing, sore throat and even dark circles under the eyes! To help relieve some of these symptoms, keep your doors and windows closed, dust and clean more frequently, and wash bedding and clothes more often. When you do step out, wearing a mask might help too.Peak Season : Winter to Late Spring -
Maple
Maple trees can be found just about anywhere in the country and are considered an important symbol of Canada. Maple trees pollinate in March and continue through June. Unfortunately, maple tree pollen is extremely allergenic and can travel for miles, making them difficult to avoid for allergy sufferers. If allergic, you might experience symptoms like runny nose, coughing, congestion, sneezing and watery eyes. For a bit of relief, close your windows and doors. Keep your house clean and shower more frequently to ensure pollen doesn’t linger after stepping outside.Peak Season : Spring -
Oak
Oak trees come from a family of 450 species and can be found all over Canada. Oak tree pollen is highly allergenic and has a long allergy season, stretching from February all the way through to July. If you’re allergic to oak tree pollen, you might face allergy symptoms like sneezing, nasal congestion, wheezing and itchy throat, nose and eyes.

Clean often and avoid bringing pollen indoors by removing “outside” clothes like shoes, jackets and hats.Peak Season : Winter to Spring
-
Ragweed
Ragweed is a weed that grows throughout Canada, especially in rural areas. A single ragweed plant can create up to 1 billion pollen grains! This usually happens around August as warm weather, summer breezes and humidity help release their pollen grains. If you're allergic to ragweed, you might face allergy symptoms like sneezing, runny nose, post-nasal drip and itchiness in the eyes, nose and throat. To help keep symptoms at bay, track the pollen count in your area, stay indoors during peak levels and plan ahead when you do step out.Peak Season : Late Summer -
Poaceae
Poaceae (pronounced “po-see-ay”) commonly known as the grass family of flowering plants. As it’s a large family (over 12,000 species), Poaceae pollen is the leading cause of pollen allergy worldwide! If you’re allergic to Poaceae, you might experience allergy symptoms like itchy throat, runny nose, sneezing, watering eyes, blocked sinuses and headaches. To help alleviate symptoms, cover up when going out to prevent unnecessary contact and remove all outside clothing when returning indoors, but ultimately, you’ll want to try to refrain from going outside if you can avoid it.Peak Season : Late Spring to Early Summer
