Frankly, I don't think Canadians view CPP contributions as a tax, to date. I wouldn't advise that discussion and debate. Canadians view the CPP as a very secure instrument of security for them. They rely on it. It's administered very efficiently at the lowest cost of all pension plans in Canada.
I don't think Canadians consider it that way. We just did a poll of our entire membership, and only 4% are concerned about taxes. They're concerned about pension security far more. They're concerned about where their jobs are going to be, and they're concerned about whether or not their children are going to have adequate facilities for their needs.
This argument about CPP being a tax is a misnomer. It's clearly a pension plan, and Canadians contribute to it, respect it, and rely on it.
