Last week, the Alberta Labour Relations Board published their second new applications report for November 2025. In it was an application for union certification.
Local 92 of the Construction and General Workers’ Union, also known as the Laborers’ International Union of North America, or LIUNA, filed the application on 7 November 2025 in behalf of workers employed by Weston Construction Alberta Ltd.
Specifically, this certification, if it goes through, would represent about 125 general construction labourers.
Weston Construction Alberta already employs unionized workers, all of which received certificates from the ALRB within the last 3 years.
Local 1325 of the United Brotherhood of Carpenters and Joiners of America, for example, has represented general construction carpenters at Weston since July 2022.
Weston’s general construction operating engineers with Weston received their certification two months later and are members of International Union of Operating Engineers’ Local 955.
General construction cement masons employed by Weston unionized in March 2023 with Local 222 of the Operative Plasterers’ and Cement Masons’ International Association of the United States and Canada.
Interestingly, according to ALRB’s list of active certificates, general construction labourers are already unionized; although the term “unionized” might be stretching it.
ALRB’s records show that they issued a certificate in March 2023 to the Christian Labour Association of Canada.
Mediation Services shows that the collective agreement CLAC members got in April 2023 expires this month. It also shows only 25 members, so 125 general construction labourers in just 2.5 years is quite the jump.
For a union to apply for a certificate from the ALRB, they must indicate support from 40% of the workers who will be covered by the proposed bargaining unit. In this case, it would be 50 workers, which is twice the number that CLAC represented when they ratified their agreement.
If the ALRB approves this application, they will hold a certification vote, which will give the workers a chance to democratically choose whether to join LIUNA.
Assuming that the 50 workers who expressed initial support for joining LIUNA actually follow through and vote in favour, they would need to convince 13 more of their fellow workers to do the same in order to win.
The ALRB has scheduled a hearing for this application, which will occur next Tuesday (the 25th). Both Weston and CLAC will be able to argue why they think these workers should not unionize with LIUNA.
Since the ALRB does not archive their new applications reports, I have included a copy of last week’s report below for your convenience.
