A strike looms for more than 9,000 workers at the Canada Border Services Agency (CBSA ), which could disrupt supply chains across North America. The work stoppage for customs and immigration agents could occur as early as Thursday after the recent release of a federal Public Interest Commission report, which sgave the workers the legal right to strike. …Mediation sessions between the union and federal officials are scheduled to begin Monday. CBSA personnel represented by the PSAC and CIU voted 96% earlier in May for taking the strike. …Workers have been without a contract for over two years, union officials said. …Mike Burkhart, vice president for Canada at C.H. Robinson, said the biggest impact would be to truck freight moving into Canada. …For cross-border operators, the potential CBSA strike is another headache on top of a potential strike by railway workers at CPKC, who recently voted for a work stoppage action.
