I have an electrical question about outlets.
Right now we are doing a little renovation in our kitchen, installing a pantry. Behind where the pantry is going to be placed is an electrical plug/ outlet. We are wanting to move it 18 inches so that the outlet is still usable right beside the pantry. I know the existing power cables are not long enough to be moved to the new location. I would have to connect a new line from the old outlet to the new electrical outlet. When I go to connect these lines, what is code for it? Can we leave the old electrical box there and just connect the wires? Do I need to install a junction box? I am guessing it will need to be accessible from inside the pantry?

We pretty much have everything we need to do this, just wanting a pros advice on what to and what is legal here in Canada...or maybe North America.

Thanks in advance!
