There are two possible situations here:
If the idea behind the depot is to be able to have year round access to fuel for land operations (Rangers/Army/Ground Air), then refueling them the way it is currently done in the Arctic by the summer resupply runs (i.e. civilian tankers that refill them using floating hoses from an anchorage near the tank farm) is sufficient and you just hire them like any other user - so long as you remember that those tanks, to be usable in the cold season (it's the Arctic, I should the the coldest of the cold seasons) have to be insulated and heated for the fuel to flow through the pumps properly.
If the idea is to have a resupply of fuel on hand for the naval vessels that will deploy there from a little before to a little after the navigation season in order to carry out surveillance and operations, then I suggest a different approach, that might end up being cheaper too. It harks back to an earlier era in the RCN (1950's to early 1980's - for those who may remember) when QHM operated on the East Coast through CFAV a coastal tanker that could be sent to refuel us in protected bays and harbours. Seems to me that if we had one or two ice breaking tankers of the same ice ratings as the AOPS/CDC, manned and operated by CFAV (I dare not suggest Federal Services

) that would sail with us up North for the season, that would be a cheaper and faster way of ensuring the fuel resupply of the ships up there. Land based depots and landing crafts can still be used for the dry goods and fresh rations.
