Instrumentation & Controls Experts

Instrumentation is all about knowing the details, many little details but it’s also about keeping the big picture in mind when it comes to any kind of project or maintenance work. To do that, you need a company that has a depth of experience and understanding of the interplay between pipefitting, instrumentation and electrical trades in order to calibrate or install control systems in a range of industries.

Our techs have that experience and know how to install stainless steel tubing, field instruments, electrical systems and calibrate equipment. Many people don’t think of other small details: mounting position, tubing slope, protection of sensitive devices, quality and turn-over documentation. The system also needs to communicate. We have the technical skills required to loop test and function test equipment, commission systems and resolve issues with integrated process controls, SCADA systems and PLCs.

In addition to this specialty, Grace is also a mechanical and electrical contractor and offers technical skills in project management, quality control and third-party monitoring, to name a few.

Grace has been around for more than 20 years and has a depth of experience in a wide number of industries from energy to oil and piping to steel and pharma. Want to know more? Give us a shout.


Our crews service several plants throughout Ontario and the GTA with instrumentation, piping, electrical and mechanical support. We are proud to have the IBEW (electrical) and UA (piping) as our labour partners.

Energy & Power

Aecon – TC Energy – Napanee Generation Station (2017-2020)

Sub-contracted to AECON during the construction and commissioning of the 900 MW natural gas combined cycle. The scope of the work included the installation of 1800 balance of plant Instruments including stainless steel impulse lines and pre-insulated sample lines. Our scope was also expanded to the re-assembly of the various critical control valves on site that had to be disassembled for welding and the various steam blows required during start-up. We also worked closely with Mitsubishi to facilitate the installation instrumentation of the gas and steam turbines.

During the commissioning phase our team of instrumentation technicians worked closely with commissioning leads to loop check all sensors and instruments that fed back into the SCADA system. Our team calibrated all instruments that were required by the client to meet regulations. We provided around the clock coverage to trouble shoot during start up to ensure successful operation of the plant.

Expansion of TSSA Certifications

Scott Marr, president, is happy to announce Grace Instrumentation is now TSSA certified for its Fuels Safety Contractor Audit Program. This additional licence will enable Grace to offer an expanded suite of mechanical services to its customers.

Last March it also received its TSSA certificate of authorization for the fabrication, assembly and repair of nonflammable medical gas piping.

This is in addition to its TSSA B31.1 and B31.3 certifications for power and process piping.
