A major construction project in downtown Halifax is Mack country. Quality Concrete, the ready-mix concrete supplier appears to be a mostly Mack operation, whether it is for their transit mixers or pump trucks. (The odd Volvo or even International has been known to sneek in.)

Lots of twin-steer Mack transit mixers. It takes two to keep the Putzmeister pumping.
