Vancouver’s Canada Post secret tunnel — a technology mistake that lasted 50 years and is now about to vanish

January 2nd, 2014 · 6 Comments

Yes, sorry, I’ve been slacking off over the Christmas holidays. But the rumballs are all gone — can’t have those for breakfast any more — and it’s time to begin tackling 2014.

To get all of you warmed up, as you’re slowly dragging your butts back into work, I’ll post a couple of the features I did over Christmas.

This first one is about the Canada Post tunnel that winds it way underneath the downtown streets, unbeknownst to many of you. It is, apparently, about to be filled in because, since Canada Post is selling its building to the B.C. pension func bcIMC, it is legally obligated to do whatever the city wishes in order to get out of its 100-year lease. And the city is saying the tunnel is too expensive to maintain and too small and impractical to do anything useful with.

I was alerted to the story by someone who knew that Richard Shannon, an interesting and Rube Goldberg-sounding guy with a specialization in developing methods for growing food in harsh climates, was trying to convince the city to save it. That led me down a long and winding path to sub-topics like growing food with artificial light, how to reinforce old concrete with new spray-on polymers and other bits of technological invention that were new to me.

Apparently Richard, and others who called, was unsuccessful in convincing anyone at the city of the brilliance of his ideas on how to salvage the tunnel and use it. But it sounds like all his calling did have one impact. When I asked Mayor Gregor Robertson  (who got to walk the tunnel its full distance from the post office to the waterfront train station and back, rats, when I and a photographer from the Globe had been turned down repeatedly) what was going to happen, he said that, although it will be filled in, the city wants the fill to be “as green as possible” — i.e. not the Portland cement that had originally been in the works.

In expensive and crowded downtown Vancouver, a historic piece of real estate sits empty. It’s been largely out of sight for decades, and now it’s about to vanish.

A 2,400-foot tunnel that runs from the city’s behemoth main Canada Post office on Georgia Street to the Waterfront train station, an early example of mail-delivery technology rendered obsolete, is to be filled in, sealing off a piece of Vancouver’s history.

The tunnel’s demise comes 54 years after it was opened as a marvel of Canada Post future thinking, and almost 50 years after new technology turned it into an expensive and quaint anachronism. This week, Canada Post said it was disposing of another expensive relic: urban home delivery. The postal agency’s once-central task of getting messages to people by hand will also fade into history over the next five years.

The decision to fill in the tunnel has dismayed a cluster of researchers and heritage advocates, some of whom have been arguing that the tunnel is a valuable asset.

“I wish I had a tunnel like that outside my office,” says Stephen Mooney, the executive director of Cold Climate Innovation in the Yukon, who had a series of discussions with Canada Post and the City of Vancouver about using it for experimental farming with artificial light. “That’s prime real estate.”

He and others say tunnels like this one – bored through bedrock, solid and strong, and in the middle of a city filled with creative entrepreneurs – offer a golden opportunity for someone to discover how to grow crops in hostile climates.

Mayor Gregor Robertson walked the tunnel last month in an effort to see for himself the passage he had always heard about. He will likely be the last non-engineer to enter: He was allowed down only after negotiations with Canada Post and extensive safety procedures were put in place for the unventilated space.

Mr. Robertson acknowledges the city has an option to take over the tunnel, “but it would be an enormous expense … to dig it out and reinforce it.”

“It’s definitely at the end of its lifespan – 60-year-old concrete that’s not reinforced, lots of water.”

Mr. Robertson says he’s also heard the ideas of how to keep the tunnel, but in the end, he says, none of them had “serious financial rigour” and “looking at how far gone [the tunnel] is, it would be very complicated.”

When Vancouver’s massive Canada Post building was being planned in the 1950s, the intention was to signal to the world the city’s future as the major transfer point between the western edge of Canada and the world beyond.

“It was a massive investment, but the country was catching up on infrastructure after the war. Vancouver was growing and, in that sense, it was quite foresighted,” says Donald Luxton, one of the city’s heritage experts. The International Style building was the largest welded-steel structure in the world at the time and included a helicopter pad on the roof.

The tunnel was to run from the new building on the cheaper, eastern end of the city’s business district, down to the CPR train station on the waterfront. The station and waterfront were the arrival points for mail and parcels from ships in the harbour and trains from the north, east and south.

Conveyor belts monitored by a man on a bicycle would efficiently whoosh bundles of mail up to the building for sorting and delivering, while other bundles would sail back to the train station for delivery across Canada or overseas.

But, like many institutions since, Canada Post didn’t grasp how quickly technology would change.

The first plane carrying mail took off in 1918. Daily air-mail service between Vancouver and Montreal started in 1939.

By 1948, any letter weighing less than an ounce was transported by airplane without an extra charge. But heavier mail and parcels still travelled by trains and Canada Post officials imagined that part of the business – which was most of it – would continue.

The tunnel opened in 1959 after five years of digging that cost $1.6-million. Within months, the postmaster-general, William Hamilton, admitted that mail handling had changed two years earlier, says John Atkin, a city historian who researched the history of the tunnel for tours he conducted through it as recently as 2005.

The tunnel was used for mail delivery until 1965 and then abandoned. The conveyor belts were stripped out and it became a city curiosity, occasionally open for film crews – check out Friday the 13th, Part VIII or The X-Files, various episodes – Halloween parties and tours.

When Canada Post sold the building last year to the B.C. pension fund, the British Columbia Investment Management Corporation, the tunnel turned from a curiosity to a liability for legal and engineering minds at the city.

The head of the city’s engineering department, Peter Judd, confirmed that Canada Post asked to terminate its 100-year lease of the tunnel and the city has asked the post office to pay the $1.3-million cost of filling it.

“It has no ventilation, no water, no access. It seems a shame but … if we were going to keep it, we would have to do that maintenance, spending a hundred grand a year for something out of use since the 1960s.”

Richard Shannon is a Vancouver-based technology entrepreneur who is currently working on systems to grow food in harsh climates like Dubai or the Arctic. He describes the tunnel as a “pretty woman to me.”

“If Canada Post doesn’t want the tunnel, we’ll take it. It’s literally a 10-acre farm,” he says. “It’s all concrete-lined, it’s in good shape.”

Mr. Shannon, who has bombarded city engineers and politicians by e-mail and phone for the last month in an effort to save the tunnel, says he has offered the city a $3-million bond – double the cost of filling the tunnel – to try to persuade officials to keep it open and allow it to be used for experimental farming.

He’s made the argument that it’s an ideal environment to try growing plants and even salmon in artificial light. Having it in central Vancouver is key, because “you’d be able to pull from all the downtown knowledge workers.”

Mr. Mooney, at Cold Climate Innovation, and Simon Fraser University’s Professor Mark Roseland say the idea of using the tunnel for farming is sound.

“Saskatchewan has used [potash-mine] tunnels for years to grow fruit trees,” Mr. Mooney said. “It’s not a new concept.”

    Interesting concept. Wonder if the plant life would alleviate the need for ventilation or if would make it worse. The proposal seems too perfect for the current administration’s green agenda that there must be something else we’re missing for them to turn it down.

    Very cool story, Frances. I’m not sure we’re so desperate for food growing space that the added costs of maintaining the tunnel’s safety would be worthwhile. Why not just protect our nearby fertile ag lands that get free sunlight, or build indoor gardening systems on industrial rooftops?

    On a related note, your readers might be interested in Seattle’s rich, complex, ugly underground history: “shipwrecks, ancient boulders and bones and lots of water”.

    It’s now coming under new scrutiny because some mystery blockage is getting in the way of tunnel-drilling for the Alaska Way freeway tunnel project.

    By that logic, PL, we shouldn’t bother curtailing our consumption of fossil fuels for a couple of decades, since we aren’t in scarcity mode yet? A research project like this would provide much needed jobs and a boost to the City’s research and innovation sector (and isn’t that a big part of the argument for spending 3-5 billion to bore a tunnel out to UBC!?). How can that be so easily dismissed, especially with someone other than the city assuming all the cost and risk?

    On a side note, a South African friend of mine commercialized mushroom growing in abandoned mine shafts in that country to great success. Faced similar skepticism and regulatory hurdles at first, but now it is seen as a win-win.

    One also has to question how the alternative – keeping the tunnel in tact but closed – could require “a hundred grand” in maintenance per year? If it is closed, what is the need for water, access and ventilation? Sounds like this number was pulled out of thin air by Judd to scare the budget conscious politicos into paying for the useless task of filling it in (also a questionable, costly, and likely unnecessary, plan of action). I seriously doubt Can Post has put $100,000 into its maintenance in the 50 years since it has been closed…

    I agree with JJJ, something must be missing from this story as it seems absurd that someone would come to table with a $3 milliion bond and “green jobs” proposal, only to be dismissed out of hand. Again, if Mr. Shannon assumes all cost and risk, what the heck does the City have to lose?

    We were asked by northern researchers to .. stop the tunnel fill in. This was a lab for the north in future growing techniques. The diabetes issue alone from inadequate food availability funds this idea many many times over. Not so rube goldberg- google – plantlab.nl tedx talk . This is very real science with a huge consequences for the north. Very sad.. tunnel safety issue was complete red herring- per 30 year tunnel mining engineer it was a 95/100 asset $2 million in filling it or $100k making it up to world best code. The leaking issue is per tunnel engineer equivalent of rainscreen on a house you design it in to most tunnels- again a complete non issue.

    The plants create basically a biosphere. Oxygen is the biggest residue of the growing. Lighting could be provided from energy via excess heat from Dunsmuir power station 5 meters from tunnel.

    LED can be powered same as the BC girl who won the google science prize…

    Again if you sat across from city “engineers” they have zero expertise – zero in what it would take. Indoor plant growing Peter is done for many reasons.. You change the “year” on the plant and basically run the growing cycle. each square foot in the tunnel can produce 50 times what best Imperial Valley farm land can produce all , organic, non gmo, 92% less water, 5 star quality , all very very doable.. You could fund Hastings park so it would be a beautiful park on the top and feed 100,000 people on the bottom. Again we are assuming that local ‘green space ‘ feeds enough people and have not even discussed people of the north that have 25 years less life expectancy than where I live. This area as the UN states the “africa of canada” (re food insecurity issues) . This was trying to address this. Uganada was even putting money to this as they wanted part of the tech. The Dubai partners have moved on feeling Vancouver were not serious on green tech.

    Funny that Vancouver has several international tunnel mining experts that consult all over the world on tunnel design and maintenance.. stating the exact opposite of what city “engineers ” were stating . This incongruence of information made this all the more frustating. Take a position from ?? and state it like it is fact so the person is filling on a technical rationale basis versus not being creative enough to figure out a good solution. ( I am sure the medical marijuana people would take it in a heartbeat if offered.)
