Collective agreements

The labour relations system in the construction industry defines four sectors for the purpose of negotiating the industrial, institutional and commercial, residential, and civil engineering and roadwork collective agreements. The agreements have common clauses dealing with union security, union representation, grievance-settlement procedures, recourse with regard to disciplinary measures, arbitration, the insurance and pension plan.

Expiry of the collective agreements and applicable working conditions

The four collective agreements expire every four years. The present collective agreements (publications/agreements) are in force until April 30, 2017. However, the working conditions agreed to continue to apply unless there is an agreement in principle, lockout or strike in the respective sector.

How negotiations work

Negotiations take place at the provincial level and for the entire labour force and all construction firms. Working conditions agreed to by the parties are applicable to the industry as a whole throughout the province.

For each sector in the industry, a sector-based employer associations is designated by the Act Respecting Labour Relations, Vocational Training, and Workforce Management in the Construction Industry (Act R-20) for the purpose of negotiation. Similarly, with regard to workers, there are five representative union associations designated by the Act to negotiate the collective agreements. To be applicable in a sector, a collective agreement must be ratified by the employer party and at least three union associations that represent more than 50% of all workers in the industry.
