With our strong national presence in the Canadian market, we pride ourselves on offering our customers extensive local service capabilities from coast to coast. For instance, other divisions of our organization include Caribou Electric in Edmonton, National Refrigeration Heating in Saskatoon, and GDI Technical Services in Quebec.

BSD Solutions was incorporated in the Province of Manitoba on January 29, 2001. On June 4th, 2018 BSD joined forces with Ainsworth Inc., one of the largest multi-trade facility services providers in Canada.

With over 1,200 employees operating in 12 offices across the country, BSD provides clients with the full range of technical-trade services needed to install, operate, maintain and optimize the performance of the majority of systems and equipment in any facility. BSD’s principal business is the supply and installation of Building Automation Systems for various buildings and campuses and enhanced building operation through the integration of multiple building systems.

Ainsworth’s depth and breadth provides new and innovative solutions to assist in managing the complex systems of a building and campus environment. BSD offers DDC and Integration products from the most recognized control system vendors.

Our offerings and qualifications as they relate to these projects are as follows:

  • Certified Tridium VYKON Systems Integrator utilizing Niagara N4
  • Certified Alerton BACnet Control System specialist
  • Certified Distech WEB Systems integrator
  • Siemens Systems integrator and value-added partner
  • Certified Johnson FX and Verasys reseller

Locally, BSD Solutions currently employs between 45 and 55 people. Our staff consists of engineers, technicians and technologists, and electricians. We have experience in integrating protocols including BACnet, LON, ModBus, JCI N2 and Siemens P2. BSD is proud to be recognized as a COR certified company and a registered CSA panel assembly shop.

BSD has completed several large automation projects in recent years. Our key to successfully delivering these projects on time is our ‘all hands on deck’ involvement. All of the people involved are employees of BSD, none of the work included in our contract scope is sub-contracted. For each project BSD assigns an Installation Supervisor who works closely with our Technical Leads to determine project schedule for BSD as it relates to the Master Schedule. BSD will provide a dedicated System Designer, programmer and technicians for this project. This selection will come from a deep local pool of talent including three System Designers, four Programmers and ten technicians.
