Canada built and used trailers with her military vehicles.
In WWII the sizes were by hundredweight (Cwt.) which equals 112 pounds. Thus: 10 Cwt. = 1/2 Ton (jeep and small truck size).
10 Cwt.From: The Pictorial History of Canada’s Army Overseas 1939-1945 page 238 Trailer, 10 Cwt. 10-P-GS-1 Composite wood and metal construction. Made in Canada. The lunette is reversible so that it can adjusted for a high (e.g. 60 Cwt. – 3 Tonner) or low (e.g. jeep) towing vehicle to help keep it level. Photo from AEDB DESIGN RECORD.
===Trailer 10 Cwt, GS Code 10-P-GS as made by Willys-Overland. From Dr. Bill Gregg reprint of a 1944 Vehicle Data Book of the Canadian Army. Willys MB-T trailer from reprint of a WWII US manual on the jeep and trailer. Trailer MB-T made by Willys in the USA during World War II. This is a 1/4 Ton trailer towed mainly by jeeps. It is 6 volt electrical system (M100 had 24 V); has NO corner handles (those came on later M100 trailer in 1950s); and NO tailgate (those came on Civilian T-3C trailers). Tires are 6.00×16 on “combat” (split) rims. During WWII Bantam also made virtually identical trailers. These are called the Bantam T-3 (NOTE: The T-3C is CIVILIAN post-war). These were classed as 10 Cwt by the Canadian Army in WWII. 1 Canadian Parachute Battalion was part of the British 6 Airborne Division and as such used some 10 Cwt Lt. Wt. trailers e.g. for Mortar Platoon and Medical.

Canada used and built many other trailers. The above are just some of the most common WWII types.
