Canadian Pacific Railway Ltd. received a 72-hour notice of intent to strike from the two unions that represent their employees.
Approximately 3400 employees are represented by Teamsters Canada Rail Conference and the International Brotherhood of Electrical Workers.
The two unions cite a lack of progress at the bargaining table and if there is no negotiated settlement, they will walk out at 12:01 a.m. on Saturday.
This potential strike comes at a bad time with the railway under pressure from shippers to move backed up grain shipments and meet the demands of the oil industry.
