The first thing you need to get is the boot carpet to go over the slippery floor of the cargo area, this would reduce the chance of things sliding around at the back, secondly, there are hook positions on the floor of the boot area where you can hook-up the cargo net hooks into to strap these items. If nissan Canada doesn't sell the boot carpet mat, just cut a piece of old carpet to shape and slot it in there.

There are 2 hook points at the back which are located pretty low, you need to flick them with your fingers for the hook points to come out of the plastic trim. Am not talking about the plastic hooks where the cargo blind attaches at the back.

I think there is confusion between the cargo net you describe which seems to work like a divider and the cargo net am talking about which is an elastic expandable one where you can slot any number of shopping bags under it and tighten it over these bags as needed. This rubber cargo net either comes with 4 or more hooks and you can buy it from any auto shop (here in Australia anyway) Nissan also has one in black, but it is pretty expensive.

I think THIS is what you need. These boot storage organizers have velcro points so they won't slide anywhere if you have a carpet at the back.
