THE PROBLEM — The US Trade War and Toronto's Exposure

1 · The problem

Toronto sits downstream of a trade fight it has almost no formal power over, and the numbers are already large and still moving. Ontario's own Financial Accountability Office projects the current US tariff regime costs the province 68,100 jobs in 2025, rising to 119,200 in 2026 if the restrictions hold, with manufacturing GDP down 8.0% in the first full year — primary metals (−17,700 jobs), auto parts, and machinery hit hardest, on a base where 40% of Ontario's manufacturing production is exported to the US. Provincial growth is projected to roughly halve against the no-tariff path (1.2% vs. 1.9% in 2026). Toronto's own exposure, filled this review at search-tier confidence: real GDP an estimated 1.6% below baseline as of Q2 2025, roughly $123 billion a year in city-facilitated US trade, and 42.1% of employment-area jobs classed as tariff-exposed in a City survey. Toronto carries this exposure through its role as the region's head-office, financial, and logistics core, and through the GTA's own manufacturing belts; the same trade dispute is named as one driver of the 2026 grocery-price forecast squeezing every household (the register's cost-of-living umbrella, X14, §1). Behind the tariffs themselves sits a wider rupture — a United States turned unreliable as both ally and market, supply-chain re-shoring, and a defence-and-procurement realignment the register's own geopolitical-resilience file already tracks. Who's hit: manufacturing workers concentrated in the Windsor-to-GTA belt, export-linked services, and — through prices — every consumer in the city. What sets this problem apart in the register's own score table is a stark asymmetry: it carries the highest urgency score of any Tier 1 or 2 problem, alongside the weakest municipal lever of any of them — 1 point of municipal leverage against 4 combined provincial/federal points. Ottawa holds trade policy and retaliation; Queen's Park holds worker supports and procurement shifts; Toronto is left with local economic development, its own Buy Canadian procurement rule, and affected-worker services. Full framing: one of this library's internal records, PR-X09.

2 · What we're asking — the question hierarchy

The primary question: What does a trade war Toronto didn't start and can't end actually do to the people who live here — and what, if anything, can a city government do about it?

Who's actually exposed, sector by sector, and how badly?

• How big is the shock, and is Toronto tracking against the province's own projection?
• The register's own named gap is exactly this: are 2026's in-year actuals tracking toward the FAO's 119,200-job projection, or diverging from it — and is anyone publishing a running scorecard a resident could actually check?
• Toronto's own headline exposure figures — GDP −1.6% vs. baseline, 42.1% of employment-area jobs tariff-exposed, $123B/yr in facilitated trade — all sit at search-tier confidence, not independently re-fetched. What does a primary-confirmed version show, sector by sector and employment area by employment area?
• Which industries are hit hardest, and which are protected?
• Primary metals, auto parts, and machinery are named as hardest hit provincially. What does that translate to concretely for Toronto's own share of the Windsor-to-GTA manufacturing belt — which firms, which neighbourhoods, how many jobs?
• Canada's counter-tariffs now cover only steel, aluminum, and automobiles — most of the 2025 retaliatory list on everyday goods (orange juice, appliances, and dozens of other products) was removed in September 2025, because the US kept letting most Canadian goods in tariff-free under CUSMA. Does that narrow counter-tariff list actually match where Ontario's own job losses are concentrated, or is it aimed somewhere else? (dayone geopolitical-resilience-trade-shocks)

Is Canada actually diversifying away from the US — or is that a mirage?

• What does the trade-diversification story actually show?
• Canada has been selling less to the US and more to other markets since 2025 — but a real chunk of that shift is a gold-price effect (elevated gold prices, gold exports to the UK spiking) rather than genuine diversification. How much of the real, non-gold diversification is actually durable, and does any of it touch Toronto-region manufacturing specifically? (dayone geopolitical-resilience-trade-shocks)
• CUSMA/USMCA didn't collapse at its mandatory July 2026 six-year review — it stays in force to 2036 under a new annual check-in process, after the US declined to renew it as written. What does that shift, from a scheduled renewal to a live annual question mark, do to a Toronto-region manufacturer's own investment planning horizon?
• What would real supply-chain rerouting actually look like for a Toronto-region firm?
• No program bank in this corpus asks what a GTA auto-parts or machinery firm's actual rerouting options are — new suppliers, new export markets, the real cost of reshoring components. That gap is worth naming plainly rather than papering over.

What are governments actually doing about it?

• What's the federal and provincial response, concretely, and is it reaching people?
• Canada's counter-tariffs on US steel, aluminum, and autos were extended to mid-2027, alongside a $5 billion fund and a $1 billion financing program for metal manufacturers. Are those support programs actually reaching the specific workers and firms the FAO's own job-loss numbers say are hit hardest?
• What's the "Buy Canadian" procurement story, and is it holding?
• All three governments — federal, Ontario, and Toronto — built temporary Buy Canadian procurement preferences explicitly tied to the tariffs staying in place, each promising to walk the preference back once the tariffs go. Is anyone actually tracking, year over year, whether that promise holds? (dayone a recommendation card)
• Canada is bound by WTO and trade-deal procurement rules that cap how far any Buy Canadian preference can go — Toronto's own rule only fully applies below a certain contract size, a "preference" rather than a ban above it. What's actually inside that legal ceiling today, and what sits outside it? (dayone geopolitical-resilience-trade-shocks)

What can Toronto's own government actually do, beyond watching Ottawa?

• What does the City control, and has it used it?
• City Council's March 2025 procurement bylaw change — Canadian-only below a contract-size threshold, a preference above it — is real and already in force. What's the actual dollar-value impact: savings redirected to Canadian suppliers, or added cost from a smaller bidder pool, and who is tracking that?
• Nobody has published what the City's own major purchases — construction materials, vehicle parts, water treatment supplies, IT — actually depend on US suppliers or tariff-hit goods, the way Toronto Community Housing did for its own purchasing in a March 2026 board report. Has the City itself done that exercise yet? (dayone a recommendation card)
• What's the municipal worker-support and communication lever, specifically?
• The register names "local economic development, Buy Canadian procurement, and affected-worker services" as Toronto's own levers — the single municipal point against four combined provincial/federal points in the score table. What does an actual affected-worker service look like for a laid-off GTA manufacturing worker today, and does Toronto have one running?
• A resident or small-business owner currently has to dig through multiple federal pages — including at least one that goes stale without warning — just to find out what tariffs are actually in force right now. Would a short, plain-language, regularly updated City page fix that, and whose job would it be to keep it current? (dayone a recommendation card)

How does a tariff in Washington become a bill in a Toronto kitchen?

• What's the direct price channel?
• The 2026 food-price forecast — 4–6% food inflation, roughly $995 a year more for a family of four — names the trade dispute as one driver alongside others. How much of that specific increase actually traces to the trade war itself, versus weather, currency, or input costs — has anyone tried to isolate it?
• What's the job-loss and income channel, and who carries both at once?
• Manufacturing job losses concentrate in specific worker profiles and neighbourhoods along the Windsor-to-GTA belt. Who exactly, and how does that overlap with the households already carrying the sharpest edge of the cost-of-living squeeze (X14) and food-bank use (H2) — is this the same population twice, or two different ones?
• Has anyone actually built the full transmission chain, rather than sketched it?
• The register's own entanglement map sketches this in outline — trade war to food and goods prices, to the cost-of-living squeeze, to deep poverty, to food banks, to shelter pressure. Building that chain out with real Toronto numbers at each link, rather than leaving it as a one-sentence chain, is unclaimed work.

What happens next, and has anyone mapped the branches?

• Where does this actually stand right now?
• The steel-and-aluminum tariff rate itself was reportedly back up for renegotiation around July 21, 2026 — after this problem's own current figures were fixed. Is there one place a Torontonian could check the live status, rather than needing to independently verify against a government source every time? (dayone geopolitical-resilience-trade-shocks)
• What are the actual scenario branches, and who's built them?
• No bank in this corpus, and no futures-program file, has built a Toronto-specific trade-war scenario tree — escalation, muddle-through, resolution — the way the futures corpus does for AI adoption or climate pathways. What would an honest, dated version of that scenario tree look like for this specific problem, and what would each branch do to the FAO's own 119,200-job 2026 projection?
• Three separate literatures track AI exposure (57.4% of jobs), driving automation (91,000+ counted drivers), and trade-war manufacturing losses (119,200 jobs at risk) — all landing on the same regional labour market inside the same decade. Has anyone actually modelled the combined exposure, rather than three separate counts that never get added together?

Who weathers trade shocks best — and everything already recommended

• Small open economies live with giant neighbours and survive their tantrums — the Netherlands, Singapore, South Korea, Mexico through NAFTA's renegotiation — what does each actually do when the big partner turns hostile: diversification machinery, firm-level supports, strategic stockpiles, negotiating posture? What does a city-region steal from a nation-state's playbook?
• Collect ALL existing Canadian recommendations on trade-war response — FAO and Bank of Canada analyses, the federal response packages, provincial supports, every economist's op-ed proposal — what has been recommended, what was adopted, and what was ignored?
• Who are the best minds on trade resilience and economic security — in Canada and anywhere — whose scenario work Toronto should be reading before its next budget, and which organizations already track this city-level exposure that the city itself doesn't?

Raised this review: thirteen of this file's twenty questions carry a [New finding, this page’s own research] tag rather than a program-bank citation. The reason is structural, not an oversight: this problem was deepened and re-scored in the same sitting the trade war itself escalated, and the four program banks checked for this review — dr3, futures, mci, livelihood — each predate that escalation and simply don't ask about it. Checked directly against each bank's own opening framing before concluding so: dr3 is built around disaster and emergency crowdsourcing response, not trade policy; mci is built around the municipal needs floor (rec, transit, food programs); livelihood is built around income architecture and the future of work; none carries a tariff- or trade-war-specific question. The futures program has no dedicated question bank at all, and its own coverage map doesn't ask about tariffs either. The one real shelf item this problem does have — the geopolitical-resilience-trade-shocks day-one brief — is current (dated 2026-07-14) and supplied seven of this file's twenty questions; raising the other thirteen well, rather than leaving this problem thin, is this review's main contribution.

3 · What we already have — the evidence shelf

One evidence stem exists that is directly tied to this problem, with a plain-language backgrounder, a Toronto-specific brief, a day-one action memo (including its own three recommendation cards, a recommendation card through a recommendation card), and a summary card:

• Geopolitical resilience & trade shocks — backgrounder · Toronto brief · not published · card

That is the honest total. Named plainly: this problem's shelf is thin relative to almost every other Tier 1 or 2 problem in the register. Adjacent material exists, but it belongs to sibling problems, not this one — gig-economy-precarious-work (backgrounder/card/leaf/brief all exist) sits under X03, not X09, even though a trade-war layoff can land a worker in gig work; the labour-market exposure literature for X01 (AI) lives in WORK & ECONOMY FUTURES — where work and livelihoods are heading, honestly scored (one of this library's own project records FUTURES THIRD PASS), not in anything filed under this problem. No flagship or deep-surface corpus exists for X09 the way it does for transit (B1) or homelessness (C2).

4 · What's unexplored

The register's own named gap is narrow and specific: "2026 in-year actuals vs FAO projection" — nobody has yet checked whether the year is actually tracking toward the 119,200-job 2026 estimate. Everything else in §2 above that carries a [New finding, this page’s own research] tag is, by definition, unexplored and shelf-less; naming the clusters rather than repeating all thirteen individually:

• Toronto's own sector- and neighbourhood-level exposure (beyond the three search-tier citywide figures) has no primary-confirmed version anywhere in this corpus.
• The real economics of supply-chain rerouting for a GTA manufacturer — new suppliers, new markets, reshoring cost — is not asked by any bank checked this review.
• The City's own procurement-preference cost/savings and its own supply-chain exposure inventory (the equivalent of what Toronto Community Housing already did) are both unpublished, per the day-one file's own account.
• No affected-worker service specifically for trade-war-displaced manufacturing workers has been inventoried, named, or costed.
• The household-transmission chain from tariff to price or layoff to a specific Toronto family's budget exists only as the register's one-sentence entanglement-chain outline, not as built-out, receipted work.
• No Toronto-specific trade-war scenario tree exists anywhere in this corpus, despite the futures program running exactly this kind of exercise for AI and climate; and no file has modelled the combined labour-market exposure of AI, driving automation, and trade-war losses landing on the same population at once.
