I believe that GFIs are often recommended in cases where there
is no ground for safety. They do not need a ground AFAIN.


They need the ground wire.

Actually, they don't.

See section 210-7(d) in the NEC, and section 26-700(9) in the CEC.

GFCIs are a legal substitute for a grounded outlet in an existing
installation where there is no ground available in the outlet box.
