In response to CPKC's stance, the Teamsters have issued a 72-hour strike notice, indicating their readiness to walk out in defense of their members' rights and safety. The union has also instructed its members to treat the company's walkout notice as if they were already on strike. Both CPKC and its competitor, Canadian National (CN), have assured that their international operations will continue, although any work stoppage could have a cascading effect on key U.S. and Mexican rail and shipping hubs.
The Canadian government, under the Liberal Party, has declined to intervene in the dispute, opting instead to allow the parties involved to resolve their differences through negotiation. This position has been met with disapproval from various business groups who had called for government mediation to avert a potential strike and its impact on the economy.
