Parks Canada is investing an unprecedented $3 billion dollars over 5 years to support infrastructure work to heritage, visitor, waterway and highway assets located within national historic sites, national parks, and national marine conservation areas across Canada.

The Nassau Mills Lock 22 concrete repair project is part of this historic investment. Work involved concrete repair to the lower lock approach walls and new concrete decking in the lock chamber. This project is preserving this important waterway asset for generations to come.
