Multiple scientific studies and expert observations across Canada reveal how climate change is fundamentally altering the traditional sensory experiences of spring, from Quebec to Alberta.

The chorus frog population in Quebec has declined by 37% per decade since the 1950s, now occupying only 10% of its historical range. Dr. Jeffrey Ethier, a University of Ottawa researcher, warns that climate-driven temperature fluctuations could further threaten their survival by disrupting breeding patterns.

Allergy impacts are intensifying as growing seasons start approximately six days earlier than in mid-20th century, according to federal data. North American pollen concentrations have increased 20% over the past three decades, reports Dr. Adam Byrne of the Children's Hospital of Eastern Ontario.

Maple syrup production faces challenges as warming temperatures affect sap sugar content. Research indicates production may decline in southern Ontario and Quebec while potentially increasing in northern regions, according to a 2019 study co-authored by Josh Rapp of Mass Audubon.

Wildfire impacts are becoming more severe, with a recent study of Canadian fires (1981-2020) showing increased frequency of conditions conducive to spring fires. This has led to significant air quality concerns, exemplified by Peace River, Alberta's 2023 pollution levels exceeding India's annual average.

Bird migration patterns show dramatic changes, with shorebird populations declining 42% since 1980. The Hudsonian godwit, which migrates 10,000 kilometers from South America, has seen its population decrease by 90% since the 1980s due to climate-related challenges.
