The UK won't be selling these subs to anyone - they have the capability to launch nuclear missiles, hence they'll be dismantled
Besides, SSBNs
aren't great for combat - they carry a smaller torpedo load than a normal attack submarine because they have to dedicate a lot of room to the missile
storage and control systems. I think (though please correct me if I'm wrong) they're also bigger than normal attack subs, too.
Besides, by the time they come out of operation they'll be worn out so Canada would be wasting its money by buying them. It's more cost effective to
replace the subs completely than upgrade them because their lifespan can only be safely increased by a couple of years at a great cost.
The US equivalent to the Vanguard-class submarine, the Ohio-class, has a longer lifespan (through upgrades) so I suppose it's more cost effective
than the UK system. However, one advantage of the UK system is that there are brand new submarines with brand new technology issued more regularly
than the US does.
The warheads (the actual bits that go 'boom') are designed, produced and stored in the UK. The delivery system (the Trident missile) is bought from
the US and maintained there. The submarines are all designed and constructed in the UK, and of course all maintainance and so forth also takes place
within the UK.
I would suspect, as others have pointed out, that the Trident missiles can operate without the use of a satellite guidance system (it'll probably be
less accurate, but accuracy isn't hugely important if you've got nuclear weapons) since we know it's possible to shoot satellites and destroy them
(as China demonstrated earlier this year). There's bound to be some sort of safety mechanism to ensure the entire system isn't disabled if a
guidance satellite is damaged or destroyed.
