In response to the US tariffs of 10 per cent imposed on imports of certain aluminum products from Canada, which will take effect on August 16, 2020, Canada intends to impose surtaxes against imports of aluminum and aluminum-containing products originating from the US, representing a proportionate amount of Canadian aluminum products affected by the US tariffs. These surtaxes will only apply on goods originating from the US, where the origin is determined as per the terms of the CUSMA, and will take effect by September 21, 2020.
