The main challenge is the time involved. The agreements are highly technical and lengthy. The rules that apply to companies such as SMEs, notably country of origin rules, are really quite complex.
Depending on their interests, the companies may need expert advice, for example. We try to support them and give them plenty of information on CUSMA.
The introduction of American tariffs forced companies to face reality after operating in a completely free trade environment for almost 30 years. They must now use CUSMA, even for products not previously subject to tariffs.
We've implemented many systems. We've set up a 1‑800 telephone line, posted information on our websites and given courses to SMEs so that they fully understand the impact of American decisions and how to get around these agreements. We've also done similar things in other situations.
