Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Description of business and basis of presentation | Description of business and basis of presentation Canadian Pacific Kansas City Limited ("CPKC" or the "Company") owns and operates a transcontinental freight railway spanning Canada, the United States ("U.S."), and Mexico. CPKC provides rail and intermodal transportation services over a network of approximately 20,000 miles, serving principal business centres across Canada, the U.S., and Mexico. The Company transports bulk commodities, merchandise, and intermodal freight. CPKC's Common Shares ("Common Shares") trade on the Toronto Stock Exchange and New York Stock Exchange under the symbol "CP". These unaudited interim consolidated financial statements ("Interim Consolidated Financial Statements") have been prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP"). They do not include all of the information required for a complete set of annual financial statements prepared in accordance with GAAP and should be read in conjunction with the Company's audited consolidated financial statements as at and for the year ended December 31, 2024 ("last annual consolidated financial statements"). Selected explanatory notes are included to explain events and transactions that are significant to an understanding of the changes in the Company's financial position and results of operations since the last annual consolidated financial statements. These Interim Consolidated Financial Statements have been prepared using the same significant accounting policies used in the last annual consolidated financial statements. Amounts are stated in Canadian dollars unless otherwise noted. The Company's operations and income for interim periods can be affected by seasonal fluctuations such as changes in customer demand and weather conditions, and may not be indicative of annual results. Operating segment The Company only has one operating segment: rail transportation. The Company's measure of segment profit is reported on the Interim Consolidated Statements of Income as "Net income attributable to controlling shareholders". CPKC's significant segment expenses are consistent with the expenses presented on the Interim Consolidated Statements of Income.
