Ending NAFTA will only slightly affect economy, researchers say
Canada’s economy would lose less than one percentage point if President Donald Trump makes good on his threat to rip up the North American Free Trade Agreement, say two new studies that suggest ending the trade treaty would do minor damage.
The total impact of ending NAFTA and reinstating tariffs would trim 0.7 to 1 per cent off Canada’s GDP according to a Bank of Montreal study, while another study by the former head of computer modelling for Canada’s foreign-affairs ministry puts the damage at 0.55 per cent.
Both studies’ authors agree these findings carry a lesson for Canadian negotiators: they can bargain with confidence and not feel pressured to sign a bad deal, because the end of NAFTA is far from a total scare scenario.
The damage would be much smaller than the financial crisis of 2008; smaller even than the impact of the soaring loonie of the late 2000s; and would be roughly comparable to the national effect of the 2015 oil-price plunge, says BMO’s chief economist.
“It’s an important risk to the outlook. It would be a fundamental change in the trading relationship. But I happen to believe we’ve dealt with much bigger challenges before, in the last 20 years,” said BMO’s Douglas Porter.
“It’s a serious risk — but it’s a manageable risk.”
His research finds the hardesthit area would be Ontario and the auto sector. It finds that other provinces have more diverse trade, like B.C. with Asia and Quebec with Europe; while provinces reliant on oil and gas would get a reprieve from lower tariffs on those products.
The paper also assumes the Canadian dollar would drop five cents, lowering the cost of investment in Canada.
But Porter cautions that his paper only addresses the secondmost-dramatic scenario: that’s NAFTA ending without the original 1987 Canada-U.S. trade agreement being reinstated, and with the U.S. reimposing tariffs.
It doesn’t map out what-if outcomes for the most dramatic scenario, one Porter sees as unrealistically remote — that’s Trump entirely scrapping international trade norms, bypassing the World Trade Organization and reimposing tariffs beyond the current international rates.
He still says ending NAFTA would hurt all three countries unnecessarily: “I don’t mean to dismiss it. One per cent of GDP is still serious stuff ... And it’s totally unnecessary ... Normally policymakers bend over backwards (to increase GDP).”
The author of the other study uses a metaphor to describe the effect: he compares it to erecting a wall down the centre of Toronto, on Yonge Street. He says people would find workarounds and, after the initial disruption, the economy would grow again — but it would produce a permanent nuisance.
“You would create a dead-weight cost, an inefficiency,” said Dan Ciuriak, a former federal official who now runs a consultancy, in an interview about his just-completed paper for the C.D. Howe thinktank.
“There would be a permanent reduction in the efficiency of the economy.”
