A chaotic, tit-for-tat trade war has hurt companies and consumers on both sides of the border, but it’s also compelled some firms to come up with creative work-arounds: finding alternative suppliers, developing new markets, rethinking product lines. But, as Dominique Ritter writes below, one MaRS startup is dealing with a late-breaking counter-tariff by leaning into the innovation at its core.

Any beaver would tell you that a good dam doesn’t just control the flow of water, it also acts as a filter.
Andrew Murray, the CEO of Aslan Renewables, understands this better than most non-beavers. His P.E.I. startup, founded in 2021, has designed a modular turbine to reanimate unused small-scale dams and provide clean, local hydropower. Keeping organisms and debris from jamming up the works is vital to smooth operations, but, with their first commercial deployment scheduled to hit Canadian waters in October, they encountered a new impediment: tariffs.
Aslan’s filtration system includes a U.S.$80,000 piece of steel called a T-intake screen. That essential off-the-shelf component — which is used in data centres and the oil and gas industry — was hit by one of Canada’s retaliatory counter-tariffs, announced on August 25. Aslan, like 70 percent of small Canadian businesses relying on ties to the U.S., was faced with a stark new financial reality.
“That was a really scary moment for us,” says Murray. “It has a huge impact for a company like ours because of our early stage. I mean, we’re still a baby company. But it also affects our total cost enormously, and we have been working for years to make sure that the cost of the system is very low.”
With no made-in-Canada equivalent on the market, it was back to the whiteboard for Murray and his team. Luckily, Aslan had already been steadily optimizing their turbine with better, more affordable components — an exercise that kept resulting in steel being swapped out for another material. In a post-tariff brainstorming session, Murray wondered, Could the filter be made out of fibreglass? The answer was yes.
In the span of two weeks, Aslan went from existential threat to designing its own filter, finding a local company to produce it and saving money in the process.
“Tariffs forced us to think deeper about our solutions,” says Murray. “And what came out is a much more sustainable answer. I feel like an idiot now. I was using a hundred-grand piece of U.S. steel! Now that just feels lazy.”
According to a September 10 report by the Canadian Federation of Independent Business, there are more than 50,000 small Canadian businesses feeling the impacts of U.S. tariffs, counter-tariffs or both. Trade disruptions are particularly onerous for small enterprises, which account for nearly half of the country’s private sector GDP and employ about a quarter of the population. How companies mitigate the mayhem is taking many forms, from drumming up more interprovincial sales opportunities to cooperating with competitors to offer made-in-Canada products.
In the end, Aslan viewed the tariff as just one more “pitfall” — Murray’s word — in the development of their solution. “That’s how we treated it,” he says, “as opposed to a more severe, deeper geopolitical problem.” And while every business is different, Murray still offers peers dealing with similar obstacles this pearl of wisdom: “Remember who you are.” — Dominique Ritter
