British shipbuilders in a Canadian investment counterfactual

If the Admiralty invested in Canadian shipbuilding around the Boer War, which British builders might establish yards there?

Vickers and Armstrong are the likeliest choices, with John Brown less likely and Cammell Laird another possibility.

The counterfactual redirects Admiralty effort during the Boer War towards investment in Canadian shipbuilding. Vickers and Armstrong are the leading candidates to establish subsidiaries. Their overseas activity in Spain provides the comparison for how such an expansion might work, with one Canadian operation on each coast proposed. John Brown is considered a less likely participant, while Cammell Laird remains another possibility. These are suggested firms and locations, rather than a claim that an investment plan existed.
