I think that when Trevor was referring to the concerns expressed by organizations—that they would lose their status if they carried on a bit too much political activity—he was describing the previous state of affairs. What the current amendments do with respect to non-partisan political activity—again, promoting or opposing a change in law or a change in policy, coming in to the House of Commons to meet with members of Parliament, etc.—is that it entirely removes those restrictions. There will no longer be a 10% limit. There won't be a bit more than 10%. It can be up to 100% of their activity—promoting a change in law—as long as it does not move into partisan support for or opposition to a political party or candidate for public office. I just want to be clear about that.
In terms of defining those activities, I think you're quite correct. If an organization was coming in to lobby a government official and was spending money in terms of a plane ticket and hotel costs, those would all be considered to be what's now defined as public policy development activities in the act.
