Canada's Coastal Environment
Canada holds the longest coastline in the world, spanning Arctic, Atlantic, and Pacific environments. Each presents distinct erosion challenges.
Arctic Coast
Permafrost Thaw
Warming temperatures are accelerating thaw of ice-rich permafrost along the Beaufort Sea and Yukon coasts, causing rapid shoreline retreat in areas that were previously stable for decades. The absence of sea ice for longer portions of the year exposes shores to increased wave fetch.
Atlantic Coast
Storm Surge & Sea Level
The Bay of Fundy, Gulf of St. Lawrence, and Prince Edward Island's red sandstone shores are subject to significant storm surge events and gradual sea-level rise. Soft sedimentary cliffs in PEI retreat measurably each year following major storms.
Great Lakes
Water Level Fluctuation
The Great Lakes experience multi-year water level cycles driven by precipitation and evaporation patterns. High water periods accelerate bluff erosion along Ontario and other lake shores, while low water periods expose beach sediment to wind erosion.
