canadian armoured regiments split their heritage between two primary sources. the first being the cavalry corps, from which many armoured regiments were created and in fact the first "armoured" regiments were titled "mechanized cavalry" regiments, and the second being the tank corps (which formerly belonged to first the infantry and then the machine gun corps). this began in 1936 with the creation of tank battalions and continued on from 1940 when many other types of regiment were mobilised as armoured units for the second world war.
