There are several challenges that we've heard. Probably the biggest one that we heard when we did our pre-consultation around NAFTA is around temporary entry of individuals. There are restrictions on the number of occupations that the U.S. will access. Things have changed a lot since NAFTA was put into place so it's about individuals not fitting into those occupational categories, challenges not getting their visas or being screened and questioned. A lot of the concern was around the business entry, but we have also heard from firms saying that inspections seem to have been tightened up. They've had an increased proportion of loads rejected for different reasons.
Again, it's just a lack of clarity on the rules and maybe different interpretations or applications of those rules. Again, businesses need to know what the rules are and they then need to know they can comply with these. I think there's been some uncertainty created because either the rules are not broad enough on the temporary entry or they're not clear enough or there's been a change in the application.
