Employment & Advancement
Updated Mar 31, 2018

In the industry, this is seen as an entry-level position.

Many optical laboratory technicians work for large, full-service labs where they perform specific tasks. Others work in smaller surfacing or edging labs. These may be linked with optical retail stores or optometrists’ practices.

Trainees may start work in the stock room of an optical lab. They may then progress to surfacing or finishing roles. After about 3 months at one task, trainees move to another task. After about 3 years, they develop enough skills to work unsupervised. This applies to both surfacing and finishing.

With time on the job, technicians may become supervisors in labs. Or they may move into related fields. For example, they may sell safety programs to industry. Or they may sell and repair optometric diagnostic tools. Some technicians study to become dispensing opticians (see the Optician occupational profile). There is a trend toward training for one position or the other.

Optical laboratory technicians are part of the larger 2011 National Occupational Classification 3414: Other assisting occupations in support of health services. In Alberta, 83% of people employed in this classification work in the Health Care and Social Assistance [pdf] industry.

The employment outlook [pdf] in this occupation will be influenced by a wide variety of factors including:

  • trends and events that affect overall employment (especially in the Health Care and Social Assistance industry)
  • location in Alberta
  • employment turnover (work opportunities that come up when people leave existing positions)
  • occupational growth (work opportunities that come up when new positions are created)
  • size of the occupation.

In Alberta, the 3414: Other assisting occupations in support of health services occupational group is expected to have an above-average annual growth of 3.1% from 2019 to 2023. In addition to job openings created by employment turnover, 169 new positions are forecasted to be created within this occupational group each year.

NOC groups often include several related occupations. Although there is labour market data for the larger NOC group, this occupation makes up only a part of that group. It means data for this occupation may be different than the data shown. For example, only some of the new positions to be created will be for this occupation. It also applies to other data for the NOC group such as number of people employed.
