It's a possibility. If the Trans-Pacific Partnership Agreement isn't signed, Canada may want to ensure that every opportunity is taken to promote the growth of its trade. As for the question you asked at the outset, I would say that ideally, the best rules in the world would be within the WTO, which has 160 member countries.
There is a limit to what can be achieved under the WTO. That's why, starting with the Canada-U.S. Free Trade Agreement, Canada has begun to add bilateral free trade agreements as a complement. In each of these cases, it helped to create a bilateral relationship that went beyond what was possible within the framework of the WTO. Indeed, it is always a matter of determining to what extent agreements with a large number of countries can be profitable. You asked if there was another solution when the first one proved impossible. I would say we should keep all options open.
For example, we are currently negotiating bilaterally with Japan, but should we also engage in bilateral negotiations with other countries in the Asia-Pacific region?
That is one of the options that could be considered.
