  1. What are seasonal allergies?

    Seasonal allergies, also known as hay fever, is a common condition that occurs when people inhale allergens in the air.

    Examples of common allergens are dust, pollen, mold, and pet hair. Although most people don’t have problems with these allergens, some people with sensitive immune systems experience an allergic reaction.

  2. Who is affected?

    About 20% of Canadians suffer from seasonal allergies.1 Anyone can get allergies and the risk is higher if one or both parents have seasonal allergies.


    1 in 5 Canadians are affected with seasonal allergies.2

  3. What are the common allergens that cause seasonal allergies?

    The most common allergen to cause seasonal allergies is pollen. When people with seasonal allergies come in contact with an allergen, their body starts to release certain chemicals which in turn cause allergy symptoms.


    Pollens are powdery substances that are released from trees, grass, and weeds. These pollens are high at different times of the year.

    • Tree pollens cause allergies in spring.
    • Grass pollens cause allergies in late spring to summer.
    • Weed pollens cause allergies in late summer to early fall.

    Seasonal allergies usually begin in spring and end in fall. This is because trees and weeds grow at these times and the pollen is very high when they are growing.
