Yes. I can give you an example of one country that is important to us: Great Britain.
We shouldn't copy everything Great Britain does, because its contribution limit is, in fact, excessive. However, in Great Britain, airtime during election campaigns is free for all parties. That means parties can reduce their spending by 50% to 60% during a campaign, considering how much they currently spend on airtime. The need to fundraise diminishes accordingly.
That's one thing that comes to mind from a financing standpoint, but it's just about the only measure in Great Britain that we should endeavour to replicate.
Other countries do it as well. We don't feel as close to them culturally speaking, though, so their experience may not seem as relevant to our situation. I opted to use Great Britain as an example because it would be hard to argue that it isn't comparable to Canada.
