General Information


“Glazier” is this trade’s official Red Seal occupational title approved by the CCDA. This analysis covers tasks performed by glaziers whose occupational title has been identified by some provinces and territories of Canada under the following names:














Erector Mechanic (Glazier)















Architectural Glass and Metal Mechanic


Glaziers measure, handle, cut, prepare, fit, install, replace and repair all types of glass and glass substitutes, typically in commercial, residential and transportation applications. In commercial applications, they fabricate and install curtain wall framing, aluminium storefront frames and entrances, structural silicone glazing (SSG), skylights and sloped glazing. In residential applications, they install doors and windows. In transportation applications, glaziers repair and replace glass products.

Glaziers also install specialty glass products such as glass railings, smoke baffles, shower enclosures, and glass and mirror walls. Other duties include layout, preparation, fabrication and replacement of architectural metal components in systems such as entranceways, windows, skylights and curtain walls.

Most glaziers work on construction or renovation projects. Others may work in specialized fields, such as replacing windows and windshields in vehicles, or installing skylights and other special glassworks in churches, museums and other establishments. Glaziers are employed by construction glass installation contractors, fabrication shops, retail service and repair shops. They may also be self-employed.

Besides working with glass, glaziers also work with plastics, granite, and other similar materials used as glass substitutes, as well as films or laminates that improve the durability or safety of the glass. Glaziers are also involved in manufacturing display cabinets and decorative windows. They may also be requested to create custom-designed glass installations for residential and commercial use.

Glaziers require good reading, writing and verbal communication skills, as well as mathematical ability to accomplish tasks within their trade. Physical strength and stamina are necessary to work with heavy glass materials, and good eyesight is needed to measure, cut and detect flaws in glass and other materials. Manual dexterity and the ability to work alone and in teams are important qualities for those working in this trade. As well, analytical ability and troubleshooting skills are important assets in this trade, especially in the context of renovation and repair projects involving older structures and products.

Glaziers work in a variety of environments; some work outdoors on construction sites while others work indoors, in shops. When working on commercial applications, glaziers are expected to work from man-lift mobile equipment, scaffolds and swing stages, sometimes at great heights, to manoeuvre glass panels that are lifted by cranes and other lifting equipment. Glaziers do a considerable amount of bending, kneeling, lifting, and standing during the installation process. There are some risks of injuries from lifting heavy materials, repetitive actions, sharp edges and broken glass.

This analysis recognizes similarities or overlaps with the work of carpenters, roofers, bricklayers, tilesetters, ironworkers and motor vehicle body repairers.

With experience, glaziers may act as mentors and trainers to apprentices in the trade. Glaziers may advance to supervisory positions such as foremen or contract managers, or set up their own shops.

Occupational Observations

There is an increase in the amount of fabrication that is done in a controlled shop environment, leading to faster installation times of unitized panels. This leads to a corresponding rise in the use of hoisting and rigging equipment, both in the shop and on-site.

Due to the improvements in the thermal capacity of modern glass, as well as greater client demand for windows that admit more natural light and permit better outside views, the industry has seen an increase in the use of larger, heavier modules. This results in glaziers having to increase their knowledge of and their ability to use hoisting and rigging equipment.

With more complex building shapes, aerial work platforms, such as specialized swing stages, are used more often. As such, glaziers need a better understanding of their operation, and must comply with certification requirements to use this equipment.

Older buildings often have outdated materials that no longer comply with established industry standards. During renovations, replacing old windows, doors and specialized glass products requires glaziers to adapt modern glazing methods to suit existing structures and maintain the integrity of the building.

Due to environmental concerns, there is greater demand for Leadership in Energy and Environmental Design (LEED) building structures, increasing the insulation value of the building. As a result, high performance glazing products, such as low-E glass, argon gas filled sealed units and upgrades in thermally-broken extrusions, are used more often. There is greater emphasis on proper membrane installation to improve the integrity of the overall building envelope.

In the residential sector, consumers are now using approved Energy Star windows to save on energy.

The safety of workers and the public is becoming a more important issue, resulting in increased safety training and more emphasis on personal protective equipment.


The CCDA and HRSDC wish to express sincere appreciation for the contribution of the many tradespersons, industrial establishments, professional associations, labour organizations, provincial and territorial government departments and agencies, and all others who contributed to this publication.

Special acknowledgement is extended to the following representatives who attended a national workshop to develop the previous edition of this NOA in 2008.

  • Scott Arcand - Yukon
  • William (Bill) K. Bauer - Manitoba
  • Marc Blakney - Alberta
  • Pierre Bordage - New Brunswick
  • Guy Charbonneau - Quebec
  • Peter Neudorf - Ontario
  • Rod O'Connor - Prince Edward Island
  • Nathan Steegstra - British Columbia
  • Steve Wicinski - Saskatchewan

This 2012 edition of the NOA was reviewed, updated and validated by industry representatives from across Canada to ensure that it continues to represent the skills and knowledge required in this trade. The coordinating, facilitating and processing of this analysis were undertaken by employees of the NOA development team of the Trades and Apprenticeship Division of HRSDC. The host jurisdiction of British Columbia also participated in the development of this NOA.
