We're in favour of ethical lobbying. The 27 citizen groups that have called for the changes have proposed a reasonable alternative, which is that significant political activity or any fundraising should face a long cooling-off period. However, a bit of the canvassing and volunteering should be allowed without any cooling-off period.
That's a reasonable alternative that protects government integrity, that will prevent unethical lobbying and that will be an egalitarian system that upholds its fundamental, democratic principle of “one person, one vote” by not allowing any one person, lobbyist or lobbying group to have more influence than any average voter.
If you're going to go to a different system than that, it is unethical and it's violating that fundamental “one person, one vote” system by allowing wealthy interests to have more influence because they can give more and are here in Ottawa, wining and dining you, etc.
