Our Ontario Engineering Company History

Originally our engineering business began as a sole proprietorship in 1996 and became Michael Sluice Gate Services Inc. in 1999 becoming more progressive and modern. The first projects began with water treatment plants for the Niagara  Region and the Region of Peel. From there they introduced themselves to the City of Toronto where they continue to acquire work at the Ashbridges Bay Sewage Treatment Plant.

Now after 20 plus years of experience, 2020 Grealey Sluice & Slide Gate Consulting Inc. continues to serve the needs of consulting engineers, general contractors, facility managers, and maintenance personnel involved with water & sewage treatment facilities all across Canada and abroad. 

Our Team

Gate Tech is most efficient with a 3 man crew on site.  We have never encountered a project that was too big for us to handle.

On large municipal projects, general contractors frequently carry us as a subcontractor responsible for the completion of gate repairs and upgrades as outlined in the contract specifications.


Michael Grealey


"His career began with Armco Canada Ltd, North America's largest and most innovative gate engineering firm in 1974.  As an independent contractor working for Armco he travelled to Egypt where he worked on the Nile Delta supervising the installation of roller gates used for irrigation in the adjacent fields.

  Starting on his own as a proprietor in 1996, creating Michael Sluice Gate Services in 1999 and becoming Gate Tech Industries Inc. in 2008, he has provided  gate erection and installation supervision for clients across Canada and abroad".
