Definitely for.
The arguments against (mostly from businesses and the Conservatives) are the same they were fifty years ago: "payroll tax", these fees payable by employers will ruin the economy, employers will stop hiring, etc... etc...
At the end of the day, employees will see a few more dollars deducted from their pay cheques. However, for every one dollar deducted, their employer also contributes one dollar and the employees now has two dollars working towards a better retirement.
And that is the key to it all. Employees get the benefit of $2.00 for every $1.00 contributed. It does not get any better than that.
Between the senior moments and the blonde moments.....
So few workers have pension plans these days that the social safety net will need strengthening when they want to retire.
We all contribute (or did contribute) a little from each paycheque and in the long run we all benefit.
That fascistic old anti-semite Henry Ford had one thing right. When he paid his assembly line workers a decent daily wage ($5 a day if I recall correctly) it was the boost needed to spread out wealth and allow his employees to buy their own cars (which was $500 at the time, I think).
Making him richer than he would have been if he had paid lower wages and sold fewer cars.
In the end, I don't think it will matter much for those taking a pension down the road. By the time they are eligible the price of things going up and up will only mean the elderly will be still just barely making ends meet. Two things are keeping the elderly above water at the present moment....a) pensions from their past workplace and b) investments they have made and for the most part the average main investment has been their homes which have gone way up in price.
As for employers and the extra they will have to pay....yes it will make a difference and especially from small businesses. Three things will happen, either people will be paid under the table or people will be laid off or prices will go up and my best guess is the latter will be the way things will go.
In the end it's all about money and profit and the consumer will pay. But look on the bright side.....they'll have that extra money from their CPP.
"I'm for it" No. No. No. You are a conservative. You cannot be "for it". 
He's for anything that even hints of putting a penny in his pocket.
"and will be peanuts."
Too late for both of us, old men in our 70's.
The changes are for the new generations, our children and grandchildren, Canadian workers without indexed defined benefits pension like you enjoy. It is a lot more difficult for most new adults to save today as we did thirty, forty or fifty years ago.
Everyone will eventually benefit from the changes. When you look at the very long term, the return on investment by CPP is superior to most investment indexes (or mutual funds). The biggest advantages for Canadians is that they have $2.00 working for them for every $1.00 coming off their pay cheques. There is no way individual Canadians can get that return with RRSP and TFSA.
A generation or two from now, most of that extra money received by seniors will be spent in the economy - and that will help everyone.
"Perhaps dual citizenship?"
The rules at eBay are simple: you reside in Canada, you must register on eBay.ca with Canadian address; you reside in USA you must register on eBay.com with US address.
You are smarter than that.
Nobody in their right mind would invest 100% of their pension in any one stock, regardless how good it did in the last twenty, thirty or forty years. Diversification has always been the only safe way to invest pension money.
The point of CPP - I repeat - is that you have $2 working for you after having invested only $1 in the plan. And the return on the plan have been well above average, well beyond what most very smart very intelligent very experienced individual investors can do - even you.
The improved CPP plan is for all working Canadians, not the few successful speculators trading in and out of the stock market. We all know most of them end up losing money.
