In general, Canadian railroads followed design practices in general similar to those of the United States. Axle loading did tend to be somewhat less on the Canadian lines. The Canadian Pacific, at least on Mikados, had axle weights of about 60,000 lbs.

The Canadian Pacific had only two classes of Mikados. The initial class was the P1 d/e, first built in 1913. This class numbered 195 locomotives, built in 1912/13. They had 63 inch drivers, 23 x 32 cylinders, 190 psi and a 50 square foot grate. Starting tractive effort was 43,400 lbs and weight on drivers was 216,500 lbs, 274,500/280,000 lbs total weight.

This was followed in the roster by class P1n, 8 locomotives rebuilt in 1946/7 from 2-8-0s initially built in 1911-13. Again, 63 inch drivers, 22 x 32 cylinders, 215 psi, 50 square foot grates, 45,000 lbs starting tractive effort. Weights were 197,500 drivers, 271,000 total.

The P2a/b/c/d were built from 1919 through 1924, a total of 60 locomotives. This class had 63 inch drivers, 25 1/2 x 32 cylinders. 200 psi boilers and 70.3 square feet of grate area, and exerted 56,100 lbs starting tractive effort. Weights on drivers were 243/249,000 lbs, total 330/338,000 lbs. These were followed by 45 P2/e/f, built between 1926-28. They had 63 inch drivers, 23x 32 cylinders, 250 psi boilers, a 70.3 square foot grate and starting tractive effort of 57,100 lbs. Weights were 249,600 on drivers, 334,000 total.

The final CP class, built between 1940 and 1974, were a group of 63 locomotives built between 1940 and 1947, P2g/h/j/k. These were still built with 63 inch drivers, but with 22 x 32 cylinders, 275 psi and 58,000 lbs starting tractive effort. Weights were 246/248,9000 lbs on drivers, 338/339,000 total. Of the last twelve, built in 1947, eight were oil burners.
