Canada’s US envoy Wiseman warns Trump tariffs raise costs, deter investment

Wiseman's framing is notable because it comes from a sitting envoy making a cost-of-capital argument rather than a diplomatic one, tying tariff uncertainty directly to corporate investment decisions. That language matters most for cross-border manufacturers and capital-intensive sectors weighing long-term commitments in the US, where policy ambiguity becomes a financing cost rather than just a trade irritant. The open question is whether the Section 232 and 338 tariff references signal a specific negotiating track or remain general advocacy.
