To put this in context, you have to look at the fact that this is 2015 data, so it's more or less now. There are over 100 million contacts a year between the public and the CBSA. Those generate 2,400 complaints—or they did in 2015. Even if that were four times 2,400, that's 0.001% of contacts leading to a complaint. This isn't going to require massive resources.
