Re: Canadian sub panels: I think they are the same here as in the U.S.. The neutral must NOT be bonded to the enclosure, unless it is fed by a separate 3-wire sub service which in that case you would have to bond the neutral and drive rods or use a plate.. Personally I agree with Check Pilot 100%.. Separate bonding conductor back to the main, and ONE connection between the earth and your neutrals. Way less headaches and chances of weird things happening.
