Who are we

The Great Lakes, St. Lawrence & Atlantic Chapter (GLSLA) encourages and facilitates the science and practice of trenchless technology for the public benefit. We achieve this by fostering education, and research and acting as a catalyst for technological and process change.

Since 1995. GLSLA has provided its members with educational opportunities, unique training and  discussion forums to foster growth and interest for trenchless technologies in Ontario, Quebec and the Atlantic provinces. We are strong believers in sharing knowledge and promoting it through a variety of venues. We have a history of initiatives that support the trenchless community and the infrastructure world.

GLSLA owes many thanks our members and volunteers, who throughout the years, have helped build this Chapter from a few industry experts with a dream into a strong Canadian network within the North American Society for Trenchless Technology (NASTT) family. GLSLA currently has just over 200 members from engineering/consultants, utilities and public works, construction, manufacturers and suppliers and academia, which also include our very valuable student members.
