HSP Engineering

Let Us Do the Math.

100% Canadian Owned Company. Established in 1984.

Our home base is in Eastern Ontario, near Cornwall, and we have regularly provided engineering services to a broad range of clients located near us, in western Quebec, northern New York State as well as northern Ontario.


HSP Engineering and Environmental Services (HSP Inc.) is a multi-disciplined engineering and environmental services firm located in Long Sault, Ontario (just west of Cornwall).  We have been providing quality professional and technical services to clients in the industrial, commercial and governmental sectors for over 30 years.  Initially, the company was established to service the rapidly expanding local industrial sector and, in particular, the pulp and paper industry.

Within a short period of time, we developed excellent business relationships not only with local plants, but also with many industrial clients throughout Ontario, Quebec, Eastern Canada and the northeast region of the United States.

In the late '90s, our interests expanded into the commercial, municipal and residential sectors.  The majority of our projects in these sectors were locally executed.  These projects have included affordable housing projects, subdivisions, roads, municipal services, environmental assessments, etc.


We are locally owned and each discipline is managed by a senior engineer who oversees the day to day tasks.


As well as overall project management, we are familiar with, and have worked with many local contractors, as well as provincial regulatory agencies (TSSA, ESA, MOE and MOL).
