Why a larger Canadian fleet might prefer more battlecruisers

Would an expanded Canadian battlecruiser force lead to demands for battleships?

Probably not; further battlecruisers, potentially at Tiger's level rather than the Indefatigable type, are considered more likely.

In the hypothetical Canadian expansion, battleships are not considered the likely next demand. More battlecruisers are the preferred possibility, including ships at Tiger's level. That choice would go beyond the cruiser-hunting role associated with the Indefatigables. Acquiring additional ships of the earlier type would differ from seeking a more powerful battlecruiser force.
