"The problem, as I see it, with referenda is the volatility of opinion based on emotion."

That is true. However, other than the Quebec referenda, Canada has not had any that I can recall.

1) Ottawa is maybe too filled with itself to find out what Canadians actually think about the issues
2) Maybe a bit afraid to find out that they have a few things wrong

For instance, I am not pro Capital Punishment. Subsequently, I think we have that right. However, I may be in the minority. I would like to know. Same for legalization of grass, abortion, gun registration, etc. I would like to know.
