Absolutely.
It goes back to your colleague's comment about the fact that we're surrounded by three oceans and our southern border is guarded by a superpower.
Clearly, the maritime approaches of this country need to be guarded carefully. That might require a submarine that has a much shorter range than one that the RCN would prefer to operate. Nevertheless our ability to deploy on a global basis is something our navy prides itself on. We've sent task groups as far away as the Persian Gulf, which is practically on the other side of the planet, and we operated submarines off the coast of North Korea in 2017.
Our ability to cover those areas off is an important consideration in terms of a task group operation.
