In 1924, the ship was renamed the SS Montroyal. Her accommodations were altered to carry 600 cabin passengers and 800 third-class passengers. On 19 April 1924, she was returned to service sailing on the Liverpool-Quebec route.
In 1926, her accommodations were again altered to carry cabin, tourist and third class passengers. She completed eight round-trip voyages in that year. In 1927, the ship was transferred to the Antwerp-Southampton-Cherbourg-Quebec route.
The Montroyal commenced her final voyage from Antwerp on 7 September 1929. Including this last voyage, she had completed 190 round-trip crossings of the North Atlantic.
On 17 June 1930, the vessel was sold to the Stavanger Shipbreaking Co. and was scrapped. The owner of the Sola Strand Hotel bought the lounge from the shipbreakers and incorporated it into his hotel as the Montroyal Ballroom. The ships woodwork is still a feature of this building which now houses the Norwegian School for Hotel Management.
