The 50th Field Artillery Regiment (The Prince of Wales Rangers), Royal Canadian Artillery was a Canadian Army Reserve artillery regiment based in Peterborough, Ontario.
The regiment exists "on paper" on the Supplementary Order of Battle.
[1][2] The regiment was created in 1960 from the merger of 50th Medium Anti-Aircraft Artillery Regiment (The Prince of Wales Rangers), RCA - originally the 57th Peterborough Battalion of Infantry formed in 1867[3] and the 45th Medium Battery, RCA[3] - originally as 45th Canadian Volunteer Militia and then as 45th West Durham Battalion of Infantry.
[2] In 2015, the Canadian Forces authorized the award of an honorary distinction to The Prince of Wales Rangers (Peterborough Regiment), if and when it is ever activated from the SOB and converted to an armour or infantry unit: the wartime badge of the Stormont, Dundas and Glengarry Highlanders (SD&GH) with the year dates 1944–45 in recognition of the role played by the PWR in the mobilization of the Canadian Active Service Force unit of the SD&GH.
[4] This badge would be emblazoned on the unit's guidon or regimental colour.
