The problem had to do with the Canada Border Services Agency, but I believe that has actually been addressed. It only has to do with the new frequencies, not for the system already in place. In Vancouver, there are plans for a new train this fall. The CBSA addressed the problem, and I believe everything has now been settled. However, I am aware of the fact that there were problems this spring.
