WINNIPEG, Manitoba (Reuters) - The massive rains that unleashed floods and mudslides https://www.reuters.com/world/americas/receding-waters-help-flood-hit-canadian-town-avoid-disaster-2021-11-18 in the Canadian province of British Columbia exposed the country’s supply chain vulnerability as crucial railways and roads were severed from the country's biggest port.
That one storm could within hours shut down a key engine in one of the world's biggest exporting nations highlights Canada's unique economic fragility. The majority of Canadian exports, which account for nearly one-third of the country’s GDP, travel to the Pacific coast to reach Asian markets.
But the supply chain route relies on two rail lines and a handful of highways through the Rocky Mountains and rugged British Columbia interior to the Port of Vancouver.
"Geology did not give Canada a lot of options and funnelling a huge amount of exports down the Fraser Canyon increases our vulnerability," said Barry Prentice, professor of supply chain management at University of Manitoba.
The Fraser Canyon, which stretches from B.C.'s high interior plateau through the Coast Mountains to the lower mainland, suffered some of the most severe highway washouts during the storm. It was also ravaged by a wildfire this summer that destroyed a town https://www.reuters.com/business/environment/wildfire-forces-evacuation-residents-small-western-canada-town-2021-07-01 and closed road and rail routes.
Building a third track through the canyon, roughly 150 kilometres (93 miles) northeast of Vancouver, is not practical since the current tracks are "literally carved into the wall of the canyon," he added.
Canada is developing a plan to adapt to climate change and this week's historic flooding underscored the need to protect export routes, Canadian Natural Resources Minister Jonathan Wilkinson said.
"What this week has shown us is some of those issues around export routes, and around goods routes...are perhaps more important than many of us had even assumed," Wilkinson told Reuters.
MORE DROUGHT AND FLOODS
British Columbia is not equipped to cope with the increasingly extreme weather it faces, said Simon Donner, professor of climatology at the University of British Columbia.
"These were rainfall totals you would expect to see in a tropical cyclone, not in November in Canada," he said.
More such disruptions in B.C. will likely force Canada to export more commodities south and east, rather than west, receiving lower prices than Asian markets pay, said Wade Sobkowich, executive director of the Western Grain Elevator Association.
Some work is already underway to make Canada's export economy more resilient.
The port at Prince Rupert in northern B.C. plans to increase its container capacity by one-third by 2023, offering a more viable, albeit much smaller, alternative for shippers to reach Asia.
In 2017, Canada's Senate released a report https://sencanada.ca/content/sen/committee/421/BANC/reports/CorridorStudy(Final-Printing)_e.pdf on the feasibility of a 7,000-kilometer northern infrastructure corridor running from the Pacific Coast, across the boreal forest past Hudson Bay and into northern Quebec.
The report concluded such a project could boost exports but take decades to complete.
Climate change is causing problems for shippers, but it could also offer solutions.
Churchill, Manitoba's seldom-used port on Hudson Bay near the Arctic may become more viable as melting glaciers open shipping lanes, Prentice said.
The season for ships travelling through the Great Lakes and St. Lawrence Seaway may also get longer before ice closes the route each winter, said Bob Ballantyne, senior adviser at the Freight Management Association, which represents shipping industries.
The solutions provide no near-term fix, however.
"We are in this weird place where climate change means both more drought and more flooding," said climate professor Donner. "The problem in British Columbia and across Canada and the world, is we are adapted to a climate of the past."
