Atlantic Towing manages a large fleet of tugs, more than twenty at last count. In addition to the three in Halifax, there are usually three based at the Strait of Canso, for ship berthing at the various piers, and to assist in transits through the Canso Canal.
When I was there late last week, there were four tugs. The usual fleet of Atlantic Fir and Atlantic Willow and Atlantic Beech, and also Atlantic Elm. When I happened by their berth, they were all tied up, with the tanker Eagle Birmingham in the background.
Atlantic Elm had been on the Mulgrave side of the Strait the day before.
