Last week, the Alberta Labour Relations Board published its fourth new applications report for March 2026. In it was an application for union certification.
Local 362 of the Teamsters filed the application on 16 March for workers employed by Amrize Canada Inc.
A decade ago, the two construction firms Holcim and Lafarge merged into LafargeHolcim, which was renamed Holcim Limited in 2021. In 2024, the Switzerland-based company announced they were spinning off all their North American assets into a separate company called Amrize.
The Teamsters already represent Amrize workers throughout the province, including in Airdrie, Calgary, Edmonton, Fort McMurray, Fort Saskatchewan, Grande Prairie, High River, Nisku, Rocky View County, and Westlock, as well as at the Sturgeon Refinery.
This application is specifically for quality control technicians working for the company’s ready-mix division in the Edmonton area, which is about 8 workers.
To submit a certification application in Alberta, workers or unions must demonstrate support among 40% of their coworkers. In this case, that would be just 4 workers.
Should the ALRB approve this application, they would hold a certification vote, during which time, workers will be able to democratically choose whether to unionize with Local 362.
Assuming the 4 workers follow through and vote in favour of unionizing, they would need to convince just 1 other fellow worker to join them if they want to win the certification vote.
The ALRB has scheduled a hearing for this application, which will occur later today. Amrize representatives will get a chance to present arguments, if they have any, as to why these workers should not be able to unionize with Local 362.
If the workers vote in favour of unionizing, one of their first orders of business will be to form a bargaining committee to begin negotiating their first contract.
Because the ALRB does not archive their new application reports, I have included a copy of last week’s report below for your convenience.
