The act needs to be reviewed because there are plenty of things missing from it. I can't say it enough: There are some major gaps.
Right now, many lobbying activities take place without needing to be registered. In addition, the means available for imposing sanctions are inadequate. Either the file is referred to the RCMP, or a report is tabled in Parliament; there's nothing in between. Furthermore, a lot of information doesn't get recorded in the register right now, when it could be.
Basically, there is a lot of room for improvement. I'd say even lobbyists agree that some improvements are needed. It's about time that the act be reviewed. It was last reviewed in 2012. In fact, the act includes a review provision. So it's not a choice, it's an imperative, a requirement. However, on two occasions, it hasn't been reviewed when it should have been.
