The blockade also puts a spoke in the wheel of just-in-time manufacturing and auto networks.

Amid delivery backlogs and bottlenecked ports, trucker blockades at U.S. border crossing points have added more pressure to an already overloaded supply chain, with the food and automotive sectors particularly vulnerable.

Since Feb. 7, protesters have cut off Canada-bound traffic on the Ambassador Bridge between Detroit and Windsor, Ont. — the busiest crossing in North America — in a show of solidarity with demonstrators protesting vaccine mandates and other COVID-19 restrictions in Ottawa.

The crossing typically handles about 7,000 commercial vehicles a day carrying more than a quarter of the roughly $775 billion in annual goods trade between Canada and the United States, according to U.S. Department of Transportation and the Office of the U.S. Trade Representative.

A group of 70 trade organizations including the Canadian Chamber of Commerce has called for a “swift and immediate clearing” of the blockade, citing the need for a steady supply of food, medical products and industrial parts.


Lanes were shut down in both directions on Feb. 7. Trucks began moving into the U.S. on Feb. 8, but not the reverse.

The delays could result in higher food prices and more spoilage, due to longer, costlier routes as trucks are diverted, allowing produce less time on shelves before getting too ripe.

“Already we are seeing delays in product of 12 to 24 hours in deliveries,” said Gary Sands, a spokesperson at the Canadian Federation of Independent Grocers.

Fruits and vegetables will arrive on grocery shelves — and kitchen counters — less fresh.

“There’s a term for that: ‘Shelflation,'” said Sylvain Charlebois, Dalhousie University professor of food distribution and policy.

“It means that it will cost more for the supply chain to distribute food and it will cost more for consumers because the shelf life…at home will be shortened, so people tend to throw away more food more quickly.”

Between $8 billion and $12 billion in agri-food crosses the Ambassador Bridge in both directions each year, Charlebois said. Some 45 per cent of Ontario agri-food imports arrive via the suspension bridge over the Detroit River, including the majority of products at the Ontario Food Terminal this time of year.

The blockade also puts a spoke in the wheel of just-in-time manufacturing and auto networks.

“For my members Toyota and Honda, they have been muddling through the last couple of days but I suspect that some production lines will be in jeopardy later today,” David Adams, president of the Global Automakers of Canada, said on Feb. 9.

Stellantis confirmed it had cut short the bulk of its shifts at its Windsor assembly plant on Feb. 8 due to parts shortages caused by the blockade, affecting thousands of the automaker’s workers. The facility resumed production again on Feb. 9.

Meanwhile at the border crossing in Coutts, Alta., traffic continues to be shut down on and off as protesters vowed to dig in for the long haul despite Premier Jason Kenney lifting the province’s vaccine passport program, effective on Feb. 9.

In the national capital, downtown arteries remain paralyzed after thousands of demonstrators took to the streets to protest pandemic measures in a rally on Jan. 29 that has stretched into a nearly two-week encampment composed of about 400 trucks, according to Ottawa police.
