Air Canada is trading 4.21% lower now at CA$26.19 on September 28, 2026; available evidence points to sector and macro pressure rather than a company-specific catalyst.

  • President Trump’s rejection of Iran’s proposal lifted oil prices, renewing concerns about fuel costs; U.S. stocks and airline shares also weakened.
  • Air Canada’s share buyback results were announced September 25, not as a new September 28 catalyst.
