This isn't to say that Guantanamo was actually useful for the national security of the US or Canada or that their complicity is equal.
The agreement with the Taliban and the withdrawal from Afghanistan, in my view, brings the authority to continue military detention of many of these individuals into question.
The chief argument to the contrary would be that these are not purely military courts and not purely military detention. Congress set up the commissions system as an Article I court, rather than this existing purely under the President's Article II war powers.

No idea if it applies to non-citizens.
Some Guantanamo detainees got compensation from the UK and Canada:
