About Us


Established in 1975 in Osgoode, Ontario, ASL began with a specialty in farmland drainage but has expanded its expertise to include, among other fundamental and relevant capabilities, a strong focus on earth works, site development and specialty projects. Ensuring up to date knowledge and a novel approach to all activities, ASL specialty projects include the first major fiber optic underground cable installation contracts in Canada, site development of prominent golf courses and road side gas line installation in Ontario.

ASL complements our broad range of skill and expertise with a talented team of Professional Engineers and Industry Specialists. The ASL team is committed to executing each project by combining our experience with the latest technology and industry innovations, renowned client satisfaction, and solid construction skills.


ASL places strong emphasis on remaining at the forefront of industry innovations, employing current technology and a driving commitment to client satisfaction.

ASL provides valued added services in a number of ways:

  • ASL projects are completed using late model excavators and bulldozers, off road trucks, wide-pad bulldozers, excavators with rototilt and specialty attachments, and a wide assortment of other high quality machinery, much of which is equipped with GPS grade control / guidance systems.
  • ASL uses industry leading software for bidding and cost estimating and equips all Foreman with iPads.
  • 3D project modelling is completed in-house, providing a detailed look at each stage of the project.
  • ASL goes beyond the traditional contractor role providing advice and expertise as a trusted advisor, providing input into strategic planning and cost saving initiatives. This approach has led to long-term relationships built on a foundation of understanding, trust and mutual benefit.

The Team

The ASL team has over 100 employees with a strong history of employee retention and promoting from within. Many of our seniors team members started with us as general laborers progressing with time.
