Docks, building slips, and steel for Canadian capital ships

How much infrastructure would Canada need to build and sustain its own Queen Elizabeth-class or later capital ships?

At least one suitable dry dock, preferably two, about two building slips for continuing construction, and industry able to supply steel and armour plate.

A Canadian capital-ship programme would require facilities for both construction and maintenance. At least one dry dock capable of taking the ships would be necessary, with two preferable. About two building slips would support a continuing rhythm of construction. The supporting industry would also have to supply steel and armour plate. That infrastructure could remain useful for a later war if properly maintained and upgraded.
