What a sudden Canadian fleet expansion would require

How would the US Navy react if Canada rapidly built the world's third-largest navy?

The first questions would concern shipyards, funding, and crews, followed by whether Canada could sustain the resulting fleet.

An abrupt Canadian rise to the world's third-largest navy would first raise questions about where the yards, money, and crews came from. The proposed mix is recognised as a balanced fleet, but the hypothetical assumes an enormous increase in construction capacity. Jokes about political cuts and neglected maintenance introduce the separate problem of keeping those ships operational. Construction, crewing, and sustainment would all have to support the larger force.
