Canadian Navy's new joint support ships faced a scheduling conflict and that the Harper government would have to choose which project had priority. On 11 October 2013, the NSPS Secretariat announced that the joint support ships would be built first,

After a brief hiatus, the development of the
Canadian Coast Guard polar icebreaker picked up again in 2021. Design updates since have included changing the propulsion layout and substituting the extra high tensile steel that was previously identified as a potential major risk item.
