The Municipality of Leamington is advancing the next phase of improvements to Seacliff Drive East, continuing the long-term renewal of this important corridor. Building on work completed in 2022, this phase of the project will focus on Seacliff Drive East between Regatta Drive and County Road 33 to support safer, more reliable infrastructure for the community.

Current Construction Stage

The project is currently in Stage 1 of construction, which includes work along Seacliff Drive East from Regatta Drive to the west side of Seneca Road.

During Stage 1:

  • Businesses and properties between Erie Street South and Regatta Drive are accessed via Erie Street South and Seacliff Drive East.

  • Businesses and properties between Seneca Road and County Road 33 are accessed via County Road 33 and Seacliff Drive East.

  • Left turns from County Road 33 to Mersea Road 1 remain available during this stage.

Further notifications will be shared as construction progresses and work moves into future stages.

Importantly, this project is part of the Northeast Trunk Sewer initiative, a major infrastructure investment that will support Leamington’s growth for decades to come. With over $41 million in provincial funding, the project will upgrade essential underground services, help enable up to 6,500 new homes, and support future jobs and economic development, all while reducing reliance on aging infrastructure.
