Canada’s Transport Minister says his patience is run out. Members of the International Longshoremen and Warehouse Union Canada working at British Columbia’s ports went back on strike yesterday (Tues), but because there wasn’t 72 hours notice, they were ordered back to work, and as it stands now, could be back on strike Saturday morning. Update: That strike notice has been rescinded)

Omar Alghabra told reporters he is disappointed that union leadership decided not to take the mediated deal to its members, but wouldn’t directly say whether back to work legislation would be considered. Instead, he said, “Thirteen days of disruptions to our largest import and export gateway to the world. We have a responsibility to act and to do something to protect Canadians’ interests and the Canadian economy.”

Prime Minister Justin Trudeau is convening the Incident Response Group Thursday to discuss the situation at B.C.’s ports.

The industry organization Canadian Manufacturers & Exporters estimates there was about $500 million in disrupted trade each day of the 13-day strike. After the strike originally ended last week, the Greater Vancouver Board of Trade estimated 63,000 shipping containers were waiting to be unloaded.
