After two such convoy duties, she was sent as escort for the ocean liner RMS Queen Mary carrying Winston Churchill and his staff to Washington.

The journey was made at 30 knots (56 km/h; 35 mph), and the ship sailed into Naval Station Argentia, in Newfoundland, low on fuel.

[6] On 10 August, again in support of the Eighth Army, Uganda and the Dutch gunboat Flores bombarded positions north of Reposto.

[7] On 12 August, Uganda, the monitor Roberts and the Dutch gunboats Scarab and Soemba shelled the east coast of Sicily.

As part of Operation Avalanche, Uganda was a member of the Northern Attack Force, which landed the British X Corps.

[9] While serving off Salerno at 1440 on 13 September 1943 she took a direct hit from a new German radio controlled 1.4 tonne glide bomb Fritz X dropped by a KG 100 bomber.

The official transfer took place on Trafalgar Day, 21 October 1944, at Charleston and she was renamed HMCS Uganda, out of respect for the British colony.

The other members of her crew of 907 comprised a carefully selected group; additional training on cruisers was provided through personnel exchanges with the RN.

Uganda left Halifax, Nova Scotia, on 31 October 1944 and steamed via the United Kingdom where following her reconstruction at Charleston, the cruiser underwent further modification.

[3] She departed the United Kingdom in January 1945 and sailed to the Pacific, stopping at Gibraltar, Alexandria, Egypt, the Suez Canal, and on via Aden and Colombo, Ceylon, to the fleet base at Fremantle, Western Australia, where she arrived on 4 March 1945.

From 11 to 13 April 1945, Uganda, as part of Task Force 57 in the Pacific, she attacked airfields and installations in northern Formosa,[11] before being redirected back to Sakishima Gunto.

The cruiser took part in the bombardment of the Japanese airbases on Sakishima Gunto between 15–20 April before the fleet was tasked to Leyte Gulf.

[13] In the aftermath of the Conscription Crisis of 1944, on 4 April 1945, the Canadian government changed the manning policy for all ships deploying to the Pacific theatre.

[12] Controversially this policy change was applied to those already there and Uganda's RCN crew were polled by the Canadian government on 7 May 1945 to determine whether they would volunteer for further duties in the Pacific War.

An embarrassed Royal Canadian Navy offered to replace Uganda with HMCS Prince Robert, an anti-aircraft flak ship that was being refitted in Vancouver.

En route to Pearl Harbor, one boiler suffered a liner collapse which would have resulted in the ship's withdrawal from active combat at any rate.

The vessel was recommissioned on 14 January 1952 as HMCS Quebec (C31) and moved immediately from Esquimalt to her new station at Halifax to replace units which had departed for Korea.

[22] From 13–25 September, Quebec and the aircraft carrier Magnificent participated in the major NATO naval exercise Mainbrace in northern European waters.

[24] On 15 June 1953, HMCS Quebec was the flagship for Rear Admiral Bidwell and led the RCN ships to Spithead for the coronation of Queen Elizabeth II.

[25][26] In October 1954, Quebec sailed on a seven-week training cruise to the Caribbean Sea and South America, making several port visits.

[28] As part of a post–Korean War realignment within the navy, HMCS Quebec was paid off on 13 June 1956 and placed in reserve at Sydney, Nova Scotia.
