However, in order to keep software up to date, systems now require the ability to connect to the internet to acquire software and licensing. Instrumentation and control technicians must be aware of the use and implications of internet connectivity such as one-way communication devices (data diodes), cyber security and firewalls.

Increasingly, process systems are seeing more automation including HMI, DCS, SCADA, PLC and open systems interconnection (OSI) systems. There is also more automation in networking/communication systems.

Some applications of wireless technologies are being introduced for functions such as monitoring process systems and meter verification.

Predictive technologies are increasingly being used in process optimization. Trends in optimization will require that the instrumentation and control technician be knowledgeable in the use of advanced diagnostics.

Tools and Equipment

Portable digital communication devices are being used to diagnose and perform tasks more efficiently and effectively.

Quality Acceptance

When installing and replacing parts, there is an increase in the need to perform quality acceptance activities and properly document and store this information to meet regulatory requirements and traceability.

Health and Safety

An increased emphasis on safety in the workplace has led to an increase in documentation for instrumentation and control technicians.

There are more safety instrumented systems (SIS) being implemented. This requires that instrumentation and control technicians be familiar with the functioning of these systems.


There is a continued increase in industry practices for environmental monitoring driven by governmental regulations. This has increased the workload of instrumentation and control technicians in areas such as reporting on carbon capture and emissions.

Industry expected performance

All tasks must be performed according to the applicable jurisdictional codes, regulations and standards. All health and safety standards must be respected and observed. Work should be done efficiently and to a high quality without material waste or environmental damage. All requirements of employers, engineers, designers, manufacturers, clients and quality control policies must be met. At a journeyperson level of performance, all tasks must be done with minimal direction and supervision. As a journeyperson progresses in their career, there is an expectation they continue to upgrade their skills and knowledge to maintain pace with industry and promote continuous learning in their trade through mentoring of apprentices.

Language requirements

It is expected that journeypersons are able to understand and communicate in either English or French, which are Canada’s official languages. English or French are the common languages of business as well as languages of instruction in apprenticeship programs.
