Canadian importers learned something uncomfortable over the past several years: a supply chain can be well run, well funded, and completely dependent on a single point of failure.
The BC floods in late 2021 cut the rail and highway links between the Port of Vancouver and the rest of the country. West coast port labour disruptions have halted container movement for weeks at a time. Rail stoppages have idled inland terminals. Drought in the Panama Canal reduced transits and pushed carriers onto different routings. None of these events were predictable individually. Collectively, they were entirely predictable.
The response from a lot of importers was to start asking about a second gateway. That is the right instinct, and it is also where the reasoning often stops, because port diversification is easy to describe and genuinely difficult to execute well.
Here is what it actually involves.
One Gateway Is a Bet, Not a Strategy
Roughly speaking, Canadian container volume concentrates heavily on the west coast, with Vancouver handling the large majority and Prince Rupert taking a meaningful share. Montreal dominates the eastern container trade, with Halifax and Saint John handling the balance and Halifax taking the largest vessels.
If all your inbound moves through one of those, you have made a bet. Sometimes it is the correct bet, and for many importers the concentration genuinely is optimal on cost. But it is worth naming it as a bet rather than treating it as infrastructure.
The exposure is not only to dramatic events. It shows up in ordinary congestion, in equipment shortages, in the fact that when a gateway gets tight everyone using it competes for the same drayage capacity at the same time. Importers who can shift volume have leverage in those moments. Importers who cannot are price takers.
There is also a routing question that gets missed. Each gateway has a natural market it serves efficiently. Vancouver and Prince Rupert reach Western Canada quickly and connect to the central Canadian market by rail. Montreal sits closest to the largest concentration of Canadian consumers and manufacturers. Halifax handles the largest vessels and offers strong rail connections inland. If all your inventory arrives on one coast and most of your customers are on the other, you are paying to move freight across the country that could have arrived closer to begin with.
Understanding which of our warehouse locations sits nearest to your customers is usually a better starting point than choosing a port and working outward from it.
The Second Gateway Costs More Than the Freight Rate
The ocean rate comparison is the easy part, and it is the part that misleads importers most often.
Adding a gateway means adding a customs process at a new location, a new drayage relationship, a new warehouse or a new set of receiving arrangements, and a new set of transit times to build into your planning. It means your inventory sits in two places instead of one, which raises your total safety stock rather than simply dividing your existing stock in half. It means your team learns a second set of procedures, and your systems have to track both.
There are volume thresholds underneath all of this. Below a certain number of containers per year through a gateway, you will not get competitive drayage rates, you will not be a priority for anyone, and the fixed overhead of the second lane spreads across too few boxes to justify itself.
Be honest about that threshold before committing. An importer moving three hundred containers a year can support two gateways comfortably. An importer moving thirty usually cannot, and the better resilience strategy at that volume is holding more inventory rather than adding infrastructure.
Where a second gateway genuinely pays, it pays for years. Where it does not, it produces a complicated supply chain that is more fragile than the simple one it replaced.
Split by Product, Not by Percentage
The common approach is to move some arbitrary share of volume through the second gateway to keep the relationship warm. Seventy thirty, or eighty twenty.
That is better than nothing and worse than thinking it through.
A more effective split assigns product to gateways based on what the product needs. Fast-moving core SKUs that you sell continuously, where a stockout costs real revenue, benefit from the gateway with the shortest and most reliable transit to your largest market. Slow-moving or seasonal inventory, where a few extra days does not matter, can take the cheaper routing. Product destined mainly for Western Canadian customers should arrive on the west coast. Product destined for Ontario, Quebec, and the eastern seaboard often should not cross the country to get there.
Done properly, this gives you two things at once. Your ordinary operations get cheaper, because each product is routed sensibly rather than uniformly. And your resilience improves as a side effect, because you are already running both lanes with real volume rather than maintaining a theoretical backup you have never actually used.
Getting product to the right region also depends on what happens after discharge, which is where intermodal service matters. Rail moves containers inland at a fraction of the cost of long-haul trucking, and gateways with strong rail connections change the economics of serving a distant market.
Diversification Fails If the Inland Side Is Not Ready
This is where most diversification plans come apart, and it has nothing to do with ports.
A container arriving at a gateway where you have no warehouse capacity, no receiving appointment, and no drayage relationship is not a diversified supply chain. It is a container accruing demurrage in an unfamiliar city while somebody makes phone calls.
Resilience requires that the second lane be operational, not theoretical. That means having somewhere for the freight to go, staff who know your product, and enough volume flowing through regularly that the process is routine when you need it under pressure. It also means being able to hold goods without paying duty immediately, which is what bonded and sufferance capability provides, and being able to transload from ocean containers into domestic equipment near the terminal rather than dragging boxes inland and paying per diem for the privilege.
Port-adjacent capacity is the practical version of this. Our Delta Port warehouse, a 210,000 square foot facility minutes from Deltaport with 36-foot clear height, more than 35 dock doors, and onsite container handling equipment, exists so that containers can be turned quickly instead of sitting in a terminal yard. The same principle applies wherever you import: the value of a gateway depends heavily on what is available immediately behind it.
Start With Your Own Data
Before making any structural change, do the analysis. Map your inbound volume by origin, your outbound volume by destination province, and your current transit and total landed cost per container by lane. A surprising number of importers discover that their existing routing is defensible, or that a single change to where they position inventory captures most of the available benefit without touching their port strategy at all.
18 Wheels Warehousing and Trucking has been moving and storing freight for Canadian importers since 1989. We operate more than two million square feet of warehousing across British Columbia, Alberta, Manitoba, Ontario, and Nova Scotia, with bonded and sufferance space, CBSA examination approval, rail siding, transloading, and our own trucking fleet connecting all of it.
If you are evaluating a second gateway, or wondering whether your first one is still the right one, request a warehousing quote and we will work through the routing with you.
