The ship was initially to have been constructed by Seaspan as part of the National Shipbuilding Procurement Strategy. However, by 2020, both the timing and location of this build had become uncertain. In February 2020, the federal government initiated a request to all interested Canadian shipyards to outline their capacity to potentially construct John G. Diefenbaker with the objective of securing service entry by December 2029.[7]
In May 2021, the government announced that two ships of a single class would now be constructed,[8] one at Seaspan's Vancouver Shipyard in British Columbia and the other at the Davie yard in Quebec, "pending the successful completion of the ongoing selection process as the third strategic partner for large ships construction under the National Shipbuilding Strategy". That umbrella agreement was significantly delayed being only signed in April 2023.[9]
The revised service entry date for the first vessel had been projected as 2030, but given the delays in reaching the umbrella agreement with Davie it was unclear whether that date could be met. The budget for this expanded program was unknown.[8] In late 2021, the Parliamentary Budget Officer estimated the cost for two ships at $7.25 billion.[1]
