The second-largest user of the type in North America was the Canadian Pacific Railway with 65 H1a to H1e class locomotives, numbered 2800 to 2864 and built by Montreal Locomotive Works (MLW) between 1929 and 1940. They were highly successful and improved service and journey times on the CPR's transcontinental routes. The third and later batches of CPR Hudsons, H1c to H1e numbers 2820 to 2864, were dubbed "Royal Hudsons" and were semi-streamlined. Royal permission was given for these locomotives to bear the royal crown and arms after locomotive No. 2850 hauled King George VI across Canada in 1939.
