The Globe and Mail reports in its Thursday edition that supply-chain disruptions come with many costs, including higher prices for products we use every day or a shortage of products on store shelves. The Globe's guest columnists Robin Guy and David van Hemmen write that the most recent threat is found in the form of impending labour disruptions across Canada's West Coast ports, including two of the three largest ports in Canada, the Port of Vancouver and the Port of Prince Rupert. These potential strikes are poised to have an immediate impact on Canadians and the health of Canadian businesses. It is cause for concern that we have not seen the federal government -- which has responsibility for ports -- signal its understanding of what is at stake. About 25 per cent of our total traded goods flow through these ports. They are Canada's largest gateway, handling over $800-million worth of cargo -- from agrifoods and potash, to critical minerals and household necessities -- every day. They are once again at risk. Given the size of Canada's West Coast ports, the impact of strikes would be far greater. The collective agreements between longshore workers have expired, with a strike set to begin as early as July 1.
