CPP and EI rates 2013 and prior years

I believe it's important to reflect on where we've been...

Every so often, usually about this time of year, I ponder the thresholds and rates as well as the maximum contributions for CPP and EI and wonder how many Canadians actually contribute the maximum for CPP.

I'm sure someone knows the statistics on that?

Note to self-employed...

If you are self-employed and earn $51,100 in 2013, you'll be required to remit $4,712.40 for CPP contributions in 2012, up $99 from 2012.
