Canadian Pollen Levels Double, Worsening 2026 Allergies as Warmer Weather and Male Trees Boost Release

Pollen monitoring across Canada suggests airborne levels have doubled in recent years, and researchers say the heavier load is worsening allergies in 2026 from hay fever to hives.
Warmer conditions linked to climate change are extending pollen-friendly weather, while this spring’s cooler start has compressed the season so early tree pollens overlap with later ones, creating a more intense burst.
Alberta has been hit especially hard after sharp swings from snow and ice to blooming trees and sun; Edmonton saw unusually high poplar pollen now overlapping with birch.
Cities can amplify the problem because heat-trapping urban surfaces raise temperatures, and decades of planting more male than female trees to avoid fruit litter have increased pollen release.
