GI-2025-48-reg1: Regulations Amending Certain Regulations Made Under the Customs Act (Transit Between International Flights)

Airlines and airport authorities at Vancouver, Toronto Pearson, and Montréal Trudeau are the primary businesses affected. Airlines will need to update their systems to transmit new data fields — specifically each passenger's transit status and first destination outside Canada — though most carriers already collect this information and costs are expected to be minor. Airport authorities will be able to decommission ITI kiosks and repurpose them as Primary Inspection Kiosks, generating small cost savings and reducing the staffing needed to oversee kiosk-based transit flows. The small business lens does not apply, as affected businesses are large commercial air carriers and major airport authorities, none of whom face significant compliance burdens — total costs across all stakeholders are estimated at less than $1 million per year.
