I believe the agency has never indicated that there wouldn't be a revenue loss from raising the de minimis threshold rate. The $66-million estimate is the amount of tariff revenue that would be collected on products coming into the country valued at between $20 and $200, which we would no longer be collecting. It's a forgone revenue collection of both customs duties and sales tax. In addition to the federal costs, there are also provincial sales tax revenues that would not be collected if we waived the collection of tax up to $200 from the current $20.
