May 27 (Reuters) - Canadian Pacific Kansas City said on Wednesday it had received a 72-hour strike notice from the International Brotherhood of Electrical Workers union (IBEW), which represents about 300 signals and communications employees across Canada. 

The company said it has prepared contingency plans that will allow it to continue. 

The IBEW did not immediately respond to Reuters' request for a comment.
