substantial changeintent broadened

The bill kept its core purpose of implementing the CPTPP but added multiple new safeguard mechanisms and tribunal procedures during passage. Forty percent of the text changed, mainly through expanded amendments to the Canadian International Trade Tribunal Act and Customs Tariff.

• New complaint categories and surtax procedures were inserted for CPTPP textile and apparel goods.

  After: “and (c) in the case of a complaint filed under subsection 23(1.03), (1.06), (1.08), (1.083), (1.09), (1.091), (1.092) or (1.096), send to the Minister a copy of the complaint and the information examined by the Tribunal in making its determination.”

• Emergency duty powers were added for serious damage from CPTPP textile imports.

  After: “Emergency Measures for Textile and Apparel Goods Imported from CPTPP Countries Order by governor in Council 77 (1) Subject to subsections (2) to (5), if at any time it appears to the satisfaction of the Governor in Council, on the basis of a report of the Minister further to a complaint filed under subsection 23(1.083) of the Canadian International Trade Tribunal Act or as a result of an inquiry made by the Canadian International Trade Tribunal under subparagraph 26(1)(a)(i.83) of that Act, that textile or apparel goods set out in Annex 4-A of the TPP , as defined in section 2 of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership , that are entitled to a CPTPP tariff are, as a result of that entitlement, being imported in such increased quantities, in absolute terms or relative to the domestic market for that good, and under such conditions as to cause serious damage or an actual threat of serious damage to domestic producers of like or directly competitive goods, the Governor in Council may, on the recommendation of the Minister, by order make those goods subject to a temporary duty, in addition to any other duty specified in this Act or any other Act of Parliament relating to customs, at a rate set out in the order, but that rate, when added to the applicable rate of customs duty specified in the CPTPP Tariff that is in effect in respect of those goods at that time, may not exceed the lesser of”

• New rounding rules for tariff calculations were inserted in multiple places.

  After: “Rounding of amounts — fraction other than 0.5 (7) If, for any goods other than motor vehicles of heading No.”

How precisely it is written

mixedChallenging the law: ModerateDisputing a charge: Hard

The bill supplies many exact definitions, numerical rounding formulas, and fixed time limits that make obligations clear. It also contains subjective phrases and open-ended powers that leave room for argument over scope.

Open to argument

• “its appropriate share of the aggregate”

  Uses an undefined subjective standard instead of a fixed formula or percentage.

• “take any other measure that the Governor in Council considers necessary”

  Grants broad residual discretion without objective criteria.

• “it appears to the satisfaction of the Governor in Council”

  Relies on the decision-maker's subjective opinion rather than an objective test.

Clear-cut

• “principal cause means, in respect of a serious injury or threat of a serious injury, an important cause that is no less important than any other cause”

  Supplies an objective comparative test that can be applied without further discretion.

• “If a reduction under subsection (3) or (4) results in a specific rate of customs duty that includes a fraction of one tenth of a cent, the rate shall be rounded down to the nearest one tenth of a cent”

  Provides a mechanical numerical rule leaving no interpretive gap.

• “which shall not exceed (a) three years in the case of motor vehicles of heading No.”

  Sets a hard maximum duration that is not open to extension by opinion.

Discretion. Significant power remains with the Governor in Council to extend orders, adopt further measures, and determine necessity, while the Minister for International Trade is named but given no detailed criteria.

Challenging the law itself. Broad discretionary clauses such as 'considers necessary' could be attacked under section 7 Charter principles of vagueness or overbreadth, though success would require showing the provisions affect life, liberty or security of the person.

Disputing a charge under it. Most operative rules consist of defined tariff items, fixed rounding steps and time limits, so disputes over whether a duty rate or order applies can be resolved by direct reference to the text.
