In an effort to obtain support for their cause, members of the Shipworkers' Trade Union picketed the unloading of a non-Canadian ship. The picketing blocked the unloading of the nonCanadian ship, and in the violence that followed, several of the crew of the non-Canadian ship were injured when assaulted by the pickets.

The union hoped to force the government to implement the recommendations of a report which had been completed earlier and which favoured the limitation of trade to Canadian ships.
