Methodology for 2006 Historical Statistics

Under the mandates that it has received the Commission de la construction du Québec (CCQ) has unique information involving employees and employers working on construction sites. This study presents detailed statistical tables on workers and employers covered by the Act Respecting Labour Relations, Vocational Training and Manpower Management in the Construction Industry (Act R-20). An annual summary, L'industrie de la construction en 2006, containing the most important data, as well as texts and graphics, will soon be available. The CCQ also publishes three quarterly trend reports: Revue de l'activité dans l'industrie de la construction, Liste des chantiers importants, and La construction en région.

The tables below deal with workers and employers covered by Act R-20, which provides a framework for the Québec construction industry's collective agreements. The CCQ oversees administration of the Act, the field of application of which covers a broad field of construction work but also involves a number of exclusions, such as residential renovation by an occupying homeowner. The data presented here concern only the covered work. A covered worker must hold a competency certificate (or an exemption) issued by the CCQ. A contractor who executes work covered by Act R-20 must both hold a licence issued by the Régie du bâtiment du Québec (RBQ) and be registered with the CCQ. Employers must then apply the conditions prescribed in one or another of the industry's four collective agreements and provide the CCQ with a monthly report in which are recorded the hours worked by each employee, the salaries paid, the contributions and dues to the social benefits plans, vacation pay, the CCQ levy, union dues, and so on. The data are drawn from these monthly reports.

The data cover only work done by workers employed by these employers. Act R-20 also allows employers, or their designated representative (one only per company), to work on all of the sites as long as he or she holds a competency certificate. In this case, employers are not themselves required to respect the conditions provided in the collective agreements and to report their own hours every month. The Act also allows certain categories of self-employed contractors (those without employees) to work on construction sites. For instance, self-employed contractors in the categories "heavy equipment contractors" and "excavation and earthmoving contractors" may work on all sites. In the other specialties, the presence of independant contractors is more limited. They are admitted only one at a time, and only for minor renovations and if they are directly hired by an employer that does not usually do construction work. Self-employed contractors are not considered in the tables.

All employees who have worked at least one hour during the year in a construction trade or an occupation (job category in which apprenticeship is not regulated) are included in the statistics. "Hours worked" refers to the hours recorded on the monthly report except for hours reported strictly for voluntary participation in the industry's social benefits. Workers who have worked in more than one trade or occupation are categorized in the priority trade - that is, the one in which they have worked more hours. Workers who have worked only in occupations are also categorized by priority occupation. There are 50 different occupations, and only consolidated data are presented here.

The present tables cover a period of up to 10 years, but most data may have been compiled since 1971. Those regarding each of the industry's four sectors, however, are available only since 1993. It should also be noted that the last year observed contains provisional data, which are revised in the following year and then become final.

The data are distributed into 10 regions, and two types of compilation are used: worker's region of residence and employer's place of business - that is, according to the work region recorded in the monthly report and corresponding to the site where the work took place.

Revision of historical data

An exceptional in-depth revision of the historical data took place in 2005, which may explain divergences with data published before that year. The historical data were completely updated and certain methods were reviewed. Notably, the quality of data on the work regions has been improved. The trades have been better identified, and therefore the occupations no longer contain workers with undetermined qualifications. The occupation categories have been modified, in particular by grouping line workers, which includes both linemen and all other workers who work on the lines. The Labelle subregion is now part of the Outaouais residency region, complying with the regulations on hiring and mobility. Finally, the age of workers is no longer calculated as of December 31; now, it is calculated as of June 1, to make the data compatible with external data sources.
