Canada, New Brunswick, and Nova Scotia Finalize $650M Chignecto Isthmus Climate Resilience Project

The decade-long initiative will protect a vital trade and transportation corridor from rising sea levels and storm surges, with $325M in federal funding contingent on Indigenous consultation and environmental reviews.

Amherst, N.S., Mayor David Kogon says sea levels are projected to rise in the Bay of Fundy over 15 to 20 years to the point where the Isthmus of Chignecto will flood, even without a storm surge.

Overview

  • The Chignecto Isthmus project will safeguard a critical economic corridor linking New Brunswick and Nova Scotia, where $100 million in goods crosses daily.
  • The $650 million project is funded equally by the federal government and the two provinces, with $325 million from Ottawa through the Disaster Mitigation and Adaptation Fund.
  • Plans include raising 13 kilometers of dykes and constructing new aboiteaux to mitigate flooding risks from climate change-induced sea level rise and storm surges.
  • The initiative will protect key infrastructure, agricultural lands, and communities, including Sackville, New Brunswick, and Amherst, Nova Scotia.
  • Preliminary engineering studies, design, and land acquisition will begin immediately, with construction slated for the latter half of the 10-year timeline.
