There are three main reasons for the evolution of costs.
One is cybersecurity. The cybersecurity reality of 2017 was not the same as it is in 2026. These are crown jewels of the Government of Canada. We pay out billions and billions of dollars. We are constantly under cyber-attack. We've had to up our game related to protections for cybersecurity, to reflect the reality of 2026.
Second, the system is 60 years old. Coding for many pieces of the system was done in the 1960s and 1970s. When you open the hood, you find things that you had no idea about, because they weren't documented properly back in 1971. As you're looking at them, that's fully expected, and that was part of the original plan.
The third element is that the scope has changed. Right now, part of the scope of BDM is the migration of 14 different contact centres that answer more than millions of calls every year. That is now part of this program, which it was not, back in 2017.
