It's a very germane question to my everyday life, so thank you for the question.
It is a complex business. I talked about dependencies. I talked about the size of some.... We're talking about half a trillion dollars crossing the border every year and 14 million shipments. The multipliers are massive, and the legacy world my colleague alluded to with coming out of CRA, Citizenship and Immigration, and other areas of departments has created a challenge from an immigration perspective. We have a lot of point-to-point connections between systems that are legacy and aged, and are on the IT list to be replaced within the next five years.
That's what we have to take into consideration when we start large projects like the ones you have here that have very specific business requirements. We have to look at those as opportunities to achieve our goals toward a town plan and not as a separate investment, which is unfortunately the way some of those investments were managed in the past. It is constant awareness of the need to converge toward a better world that pushes us to intercept as many of those investments as we can.
