ok first off run a ground wire to your main panel to pick up your sub panel so you DON'T get a ground loop thats dangerous and can make weird things happen 2. NEVER use rebar as a ground rod because it WILL corrode and you don't want your rebar thats holding your house together to corrode.

....you make it sound like grounding the rebar will make it corrode? In the 4 years i have been doing electrical i have NEVER had to replace a ground connection to a rebar. In a detached building or a garage even built onto a manufactured home or what not they make the builder stub up a rebar for the ground and in some cases they make you use the rebar for a ground. I have never seen a rebar thats being used for a ground corrode...its a really good ground. By the way if you are running wire in a conduit from your main panel to your garage and its detached...or even if it is attached you have to run a 4 wire to your panel...which has a ground in it.

rebar will rust and make a poor connection point DONT do it you need a proper ground rod and and some cases you need to drive a 8 foot ground rod then move 4 to 5 feet away and drive another one and connect the two in a commerical application they run ground completely around building to help with lighting strike and complete a very good grounding system Dont skimp on the ground system ITS YOUR LIFE ground ground bond bond bond

budy i have only been doing electrical for three years thats not much i know but what i do know is REBAR WILL CORRODE ground rods do all the time iv seen what a ground rod looks like when its been under ground for years and theres NOTHING left its not just from being in the ground but its from electrolysis from your current from an unbalanced neutral going back to ground. I never would have thought a inspector would let that pass using a rebar as a ground rod. Out here if you wire up a 200 amp service you HAVE to have 2 ground rods and they have to be 5 or 7 feet between the two. And for satelites and towers you have to have a grounding grid of something like 6 ground rods all bonded together and by bonded i mean welding the wire to the rod. I don't think american code is much different than Canada almost all of our voltages are the same.
