Trump begins a wave of about 25 tariff letters (July 7-12, 2025): Japan and South Korea first on July 7, Brazil on July 9, Canada on July 10, the EU and Mexico on July 12

Trump posted the letters on Truth Social, setting new tariff rates from August 1, 2025: 14 on July 7 (Japan and South Korea first), eight more on July 9 (including Brazil at 50%), Canada's 35% letter to Carney on the evening of July 10, and the EU and Mexico (30% each) on July 12. The Associated Press list covers 25 recipients, with rates from 20% (the Philippines) to 50% (Brazil). Our note: the letter to Canada was part of this global wave, not a Canada-only step; its 35% rate was among the higher ones.

Claims that rest on this event

ComplicatesMechanism
Canada stands out not for how much it pays in US tariffs but for the tools used against it. Its effective tariff rate is at the low end of all trackers, and the Section 338 tariffs cover about 5% of its shipments. What is unusual is the first-ever use of Section 338, import bans, exclusion from US government purchasing, and trade talks cut off twice. Brazil shares part of that. Canada's retaliation and its deal with China coincide with the gap, but neither can be shown to cause it: countries that didn't retaliate, such as Brazil, India and Switzerland, were hit as hard or harder.
Canada's 35% letter was one of ~25: a global calendar.

Tested hypotheses: a thought experiment

Suppose Washington foresaw and wanted this. Would this event look any different than under the rival readings? This is a deliberately contrarian test, explained here, not the author’s belief. Judgments, not measurements.

Judged to fit the plain self-interest reading better than the foresight reading. What this means

Reading	Fit	Why
I0a Accident Tested hypothesis (intent)	Fits weak	Canada's letter came as one of about 25 in a global wave set on a common template, consistent with a general tariff drive in which Canada is one target among many.
I0b Plain self-interest; Canada's response not considered Tested hypothesis (intent)	Fits weak	A global wave of tariff letters is consistent with plain US self-interest applied to everyone, Canada included.
I1 Foreseen and welcomed, not the reason Tested hypothesis (intent)	Neutral weak	Canada's 35% letter came as one of about 25 in a global wave; this fits these readings equally.
I2 Foreseen and wanted (this level or higher) Tested hypothesis (intent)	Against weak	Because the Canada step was part of a global template rather than a Canada-specific move, it fits a design aimed at Canada's particular response somewhat less well, without ruling it out.
I3 Worked-out plan with specific targets Tested hypothesis (intent)	Against weak	A worked-out Canada plan would be expected to show Canada-specific steps; here Canada's letter followed the same global template as two dozen others.
R-annex Annexation Rival reading	Neutral weak	Canada's 35% letter came as one of about 25 in a global wave; this fits these readings equally.
R-frag Fragmentation Rival reading	Neutral weak	Canada's 35% letter came as one of about 25 in a global wave; this fits these readings equally.
R-weaken Weaken-Canada rivals (annexation or fragmentation) Rival reading	Neutral weak	Canada's 35% letter came as one of about 25 in a global wave; this fits these readings equally.
