Canada Post said operations will resume at the national postal service on Tuesday after the nearly monthlong work stoppage

As the nationwide postal strike hit the four-week mark Friday, the federal labour minister said he'll send the dispute between the postal service and its workers to the Canada Industrial Relations Board.

Canada postal workers have now been on strike, walking the picket line for a month. As Megan King reports, a decision by the CIRB will determine whether they will be ordered back to work — which could happen as soon as Monday.
