"The Trump administration’s announcement of punitive tariffs on Canadian steel and aluminum means we’re into a full-blown economic and political war with the Americans"

The Trump administration’s announcement of punitive tariffs on Canadian steel and aluminum means we’re into a full-blown economic and political war with the Americans.

Prime Minister Justin Trudeau’s tough statement Thursday afternoon that these tariffs are unacceptable and an affront to all Canadians is unprecedented for its direct and unrestrained criticism of an American president and his administration by any Canadian leader. In answering the press, Mr. Trudeau said that President Donald Trump’s actions represent a “turning point” in Canada-U.S. relations.

The descent into full-scale economic warfare with the Americans had been evident for some time, notwithstanding overly optimistic comments by some observers dismissing Mr. Trump’s periodic threats and fits of rage against Canada (and Mexico) as just so much bombast. Some bombast.

It’s no surprise that Mr. Trump would use tariffs as his weapon of first choice, recalling his bellicose inaugural address with its unapologetic “America First” chant. Tariffs are easy to apply, especially if you disregard treaty obligations; they can be designed to appease domestic constituencies and inflict maximum pain on foreign trading partners.

The duties will have an immediate negative impact on Canadian steel and aluminum industries, forcing production cutbacks and threatening thousands of Canadian jobs.

Added to this is Mr. Trump’s threat to target Canadian auto imports down the road.

The countermeasures Canada announced have been designed with the same pain-inflicting objectives, even if Canada’s relative economic size means Canadian surcharges won’t inflict the same level of absolute discomfort on the U.S. economy. Nevertheless, Canada has little choice but to go down that road.

All of this heralds a long, bitter and painful battle with the Americans and ominously darkening relations on a scale broader than tariffs, a destabilizing and destructive situation unprecedented in more than 150 years of shared history.

There have been periods of tense political relations between the two countries before. There was John F. Kennedy’s intense dislike of John Diefenbaker and the then Conservative government’s refusal to accept nuclear-armed missiles on Canadian soil. There was tension with the Johnson and Nixon administrations during the Vietnamese war. George W. Bush was angered when Paul Martin backed out of shared North American missile defence at the last hour.

These earlier episodes can be chalked up to bilateral irritants and divergent interests that emerge from time-to-time in a complex relationship. But these were of an order materially different from the open anti-Canadian hostility, contempt and disregard exhibited by the White House in announcing the tariffs.

Canada of course isn’t alone in being targeted by Mr. Trump’s protectionism. The moves are part of an American trade strategy aimed at adversaries and allies alike, the EU included, grounded in Mr. Trump’s xenophobic world view and aided by the likes of John Bolton, Peter Navarro, and Robert Lighthizer.

Beyond American bilateral relationships, actions by the Trump administration denigrate the multilateral rules-based system and disregard U.S. obligations under that system. Foreign Minister Chrystia Freeland repeatedly described the duties as illegal, which is correct.

Recourse to rarely used WTO national security exceptions is only permitted in time of war or other international emergency, a situation that requires objective fact, not some unbridled right of unilateral declaration. Using the guise of national security, as Ms. Freeland has said, is “specious and unprecedented” in trade law terms.

Mr. Trump is pillaging the temple of the global trading system so painstakingly constructed over decades, largely as a result of U.S. pressure – sometimes more benignly and ironically described as American leadership.

Where do we go from here? In the immediate term, Canada will proceed to retaliate with its own surcharges against $16-billion of U.S. imports, as Mr. Trudeau stated. We will need steely (forgive use of the word) resolve and steadfast political will at all levels as we move down this perilous path.

Turning to NAFTA negotiations, there’s no doubt the American actions have jeopardized any residual amount of good will at the negotiating table, an element requisite to cementing any mutually agreed trade deal. The NAFTA exercise thus could be irredeemably harmed by this latest U.S. move.

Should negotiations be suspended, whether the three countries can get back to the table will be an open question. This leads to the possibility of Mr. Trump triggering the U.S. intent to withdraw, compounding the increased political and commercial uncertainties facing Canadian business.

As to broader political matters, the conduct of neighbourly relations with the U.S. under these unprecedented circumstances (a term used by Mr. Trudeau several times during his news conference) will be challenging. By turning aside all of Canada’s representations, Mr. Trump and his cohorts have jettisoned the idea that allies are important, especially ones that have been as remarkably steadfast as Canada over the years.

It will require teeth-clenching and diplomacy of the highest order for Canada to maintain any semblance of a friendly relationship with Washington during the remaining years of the Trump administration.

At the same time, Canada needs to be armed and girded for the vicissitudes of trade and economic war with our largest trading partner, because that’s where we’re heading.
