LAVAL, Quebec - Canada Post workers have targeted a Laval office of the Purolator delivery service, blocking doors and slowing down operations Tuesday morning.

Canada Post workers, embroiled in a labour dispute, feel that Purolater – owned by Canada Post - is undermining their cause by taking over much of the deliveries usually performed by postal workers.

The Canada Post workers reported that the occupation of the truck depot significantly hindered Purolator's deliveries. They reported that as of 8:15 a.m. Tuesday, fewer than half of Purolator's fleet had left the centre a time when all trucks would normally be on the road.

Workers returned to their picket lines after all of the trucks left the Purolator distribution centre
