Mr. Speaker, that is actually a very good question. In any trade agreement, access to thousands, perhaps hundreds of thousands, of products is open through the agreement. If the legislation of both countries, or multiple countries, in that trade agreement is not harmonized in the way they regulate technology and the way they regulate food, for example, that could actually end up causing an unnecessary barrier to trade, a technical barrier to trade.
Incorporation by reference allows legislators in each country to incorporate each other's legislation, which means that all of those products that are meant to be traded without tariffs would be able to be done that way.
