MONTREAL - Truckers are warning that a Saturday deadline requiring them to be vaccinated in order to enter Canada will put additional strain on supply chains amid the latest COVID-19 surge and severe worker shortages.

Starting this weekend, truck drivers and other essential workers seeking to cross into the country will need to be fully vaccinated, and will be turned away — or, if they're Canadian, required to quarantine — unless they present proof.

About 10 per cent of the 120,000 Canadian big-riggers who traverse the border may not be able to work those routes because they haven't been jabbed, said Stephen Laskowski, head of the Canadian Trucking Alliance.

The vaccine mandate has started to impact operations.

"There are many of our members who have already said they will not be dispatching unvaccinated drivers across the border," Laskowski said.

Transport companies never opposed the vaccine mandate; "it's the timing of it," he said, citing supply-chain pressure points ranging from clogged ports to sick workers and inflation.

However, the new rule may have encouraged reluctant workers to roll up their sleeves. One Montreal-based logistics company offered a $10,000 bonus last month to all drivers who received their first vaccine dose by mid-January in the hopes of retaining employees and boosting inoculation rates.

Another, Ontario-based Titanium Transportation Group, which boasts a fleet of 800 tractors, says 95 per cent of its drivers are fully vaccinated.

"More than likely there's no good time, right? They've had this exemption for quite a long time. So maybe this is the right time," CEO Ted Daniel said.

Nonetheless, trade groups are calling on Ottawa to postpone the Saturday deadline, which was announced in mid-November.

Recent flooding in British Columbia and China's "zero-COVID policy" have added to supply-chain bottlenecks, said the Canadian Manufacturing Coalition in a letter signed by 18 industry association heads, who are asking for a delay. The Petroleum Services Association of Canada said the vaccine mandate will "only aggravate things further."

Food and agricultural products could also feel the squeeze.

Nearly two-thirds of the roughly $21 billion in agri-food imports that Canada receives from the United States each year arrives by truck, according to Sylvain Charlebois, a Dalhousie University professor of food distribution and policy. The reliance on U.S. products is especially high in winter.

"I have to say I'm a little bit concerned, because we're already seeing empty shelves in stores right now. We just don't want more," he said.

"The stakes are much higher on our side than on the American side, because America will buy raw materials to be processed domestically, whereas in Canada most of the products that we buy from the Americans are market-ready, like produce and processed food."

The U.S. is set to enact its own vaccine mandate for essential workers at the border on Jan. 22.

American Trucking Association chief economist Bob Costello estimates that just under half of the 28,000 U.S. drivers who regularly haul freight across the border will no longer be able to do so, posing a further threat to the smooth supply of goods.

“We want everybody to get vaccinated. We're not anti-vax. But this is a group of folks, for whatever reason — I'm not going to point fingers — they’re not vaccinated at a high rate," Costello said, citing "very independent-minded" drivers.

Larger truck companies can likely absorb the Jan. 15 restriction, rerouting the handful of drivers who aren't vaccinated to domestic trips. But smaller transport outfits that rely on independent truckers — as well as smaller exporters that buy space in carriers to move their goods — may be hit harder, said Dennis Darby, president of the Canadian Manufacturers and Exporters.

He said he’s had more companies calling about the trucking rules than with concerns about the effects that Omicron is having on their operations.

“We want everyone to be vaccinated. We've made exceptions for health care workers who weren't vaccinated. … but I would argue these guys, truckers, are essential workers as well and maybe there's a way around it for a period of time," he said.

Labour shortages stemming from Omicron are indeed affecting essential sectors, said Laurel Lennox, spokeswoman for federal Transport Minister Omar Alghabra.

"We also know that vaccination is the best way to fight this pandemic, to protect the health and safety of workers, and to keep our economy moving," she said in an email.

Conservative Leader Erin O'Toole warned last week that "we’re going to see prices skyrocket for groceries, for everything," and that the Liberal government's vaccine mandate would spark "division and pink slips.”

The job vacancy rate in transportation and warehousing hit 5.2 per cent in the third quarter of 2021, below the average of 5.4 per cent across all sectors, according to Statistics Canada.

However, the Trucking HR Canada trade group said the number of vacancies among truck drivers in particular rose 20 per cent from the second quarter of 2020 to 22,990 jobs, for a vacancy rate of about eight per cent between July and September.

Days before the Saturday deadline, the Canadian Trucking Alliance said the government hasn't provided all the details with regards to compliance.

The ArriveCan app "may be used exclusively," Laskowsky said. "I do not know at this point."

The ArriveCan app or web portal is the only way to submit vaccination information, including for truckers starting Jan. 15, Canada Border Services Agency spokeswoman Rebecca Purdy confirmed in an email. Further proof of vaccination may be required at border, she wrote.

The agency will have "mechanisms" in place to facilitate cross-border trucking, but "will not compromise the health and safety of Canadians for the sake of border wait times," Purdy said.
