The Globe and Mail reports in its Thursday edition that Canadian cities are using the tools at their disposal to mount a defence against U.S. President Donald Trump's threat of 25-per-cent tariffs on almost all Canadian goods. In a Globe special, Frances Bula writes that many of them have begun re-examining their procurement budgets. Vancouver, for example, reported that it buys about $6-million worth of goods from American suppliers; Amazon is one of the bigger ticket vendors at $385,000 in payments from the city in 2023. In Toronto, less than 10 per cent of its procurement is estimated to be from U.S. sources. Multiply those small amounts by the hundreds of cities across Canada and it starts to have an impact. Earlier this month Surrey, B.C., Mayor Brenda Locke deferred a vote on a $700,000 contract with an Indiana company for mobile bleachers, pending research on whether it can legally cancel the deal. In Vancouver, council passed a motion directing staff to look at dropping American suppliers and switching to local or Canadian businesses. In Montreal, Mayor Valerie Plante said her city would no longer make any purchases from Amazon and threatened to impose a 25-per-cent "penalty" on other American suppliers.
