The 7th Medium Regiment, Royal Canadian Artillery, was one of six Canadian medium regiments that saw service in Britain and continental Europe in the Second World War, the others being the 1st, 2nd, 3rd, 4th, and 5th Medium Regiments. (There was no 6th Medium.)

The 1st, 2nd and 5th Mediums served in Italy, while the 3rd, 4th, and 7th were in northwest Europe. Three of these units (1st, 4th, and 7th) were each equipped with sixteen 5.5-inch (140 mm) guns, firing 100-pound shells, while the other three had 4.5-inch (110 mm) guns firing 60-pound shells.

Medium regiments were not part of the artillery component of the individual infantry or armoured divisions as were most field regiments (25-pounder guns) but were classed as "Army" troops and were available to support any formation which needed the fire of heavier guns.

The 7th Medium Regiment was raised in September 1939 with the mobilization of four Ontario militia field artillery batteries: the 12th (London), 45th (Lindsay), 97th (Walkerton) and 100th (Listowel). In the period from then until February 1941, during which time the regiment was at Petawawa, there were a number of organizational changes from which emerged the 7th Army Field Regiment, RCA, consisting of the 12th, 45th and 97th Batteries.
