That's an interesting question that I don't often get asked.
There are things that I have to look at, for example, budgets, estimates and so on. I also have to respond to requests from the four committees that are named in my enabling legislation. I tend to also value other committees that request something of me very highly. That's usually top of the list.
After that, I go by interest of parliamentarians. It's a combination of interests from parliamentarians and items that have a big price tag attached to them. There are lots of amounts at stake and big dollars. This qualifies on two counts, with the big dollar amounts and the interest from parliamentarians from multiple parties.
Finally, individual parliamentarians or items that are less expensive or have less revenue-generating capacity tend to be lower down the totem pole, unfortunately.
