Quebec's labour tribunal has given union accreditation to workers at an Amazon warehouse in Laval, Que., a first in Canada.

Workers at the DXT4 warehouse, located in Laval, a suburb north of Montreal, had been working toward unionizing with the Confédération des syndicats nationaux (CSN) for two years.

The CSN filed an application with Quebec's Administrative Labour Tribunal on April 19 to represent some 200 employees. The decision came down Friday.

Caroline Senneville, the CSN's president, said employees were dissatisfied with what they described as a hectic work pace, low wages, and inadequate health and safety measures.
