...The US is the only country I've found that applies a 'WEP' type modifier (but there may be others?). Some countries offer a tax reduction on pensions from another country (such as from the US) received in the foreign country.
I was referring to CPP and I actually don't need any CPP credits to qualify for Social Security benefits. My work history in the US is sufficient.
Based on the helpful link provided, I looked at how my Social Security benefits will be impacted--since I only have 28 years of "substantial earnings", I'll get 80% (instead of 90%) of the first slice of my average monthly earnings. Not a big impact, but I agree, it's a bit of a stretch to call some miniscule Canada Pension Plan benefit a "windfall".
But at least Old Age Security will not be affected by collecting Social Security and vice versa. For people in Canada who qualify for the full amount, it's a nice extra $500 a month (fully taxable). I'll get some pro-rated amount based on my number of years resident in Canada before age 65.
