That's a great question. It's a difficult process, as you might expect.
We did three steps. One, we looked around the world to see how other jurisdictions prioritized, and we tried to get some best practices. Then we sat down with each municipality, showed them our proposed methodology, and asked if they had any advice, comments, or concerns with the way in which we were about to undertake this process. The third step was to ask if we could have all of their inputs to the projects in their municipalities and then to say, “Let's agree that these are the right inputs so that when we put them through the decision-making model, we can agree that all the inputs were what we all supported at the outset”.
The final step, which is the next piece we have to do, is to sit down with them and say, “Here are the outcomes, this is what it says for our next round of projects in the Toronto region over the next six to fifteen years, and these are the kinds of solutions we think are the priority solutions”.
