Yes, pretty much the same thing.
Just arrived in the mail last week.
It's to be phased in over the next 4 years. But good news for the City of Toronto I guess. They will establish a new mill rate, but you can bet your sweet ass that you (and me) are going to be paying a shit load more taxes.
Interesting to note that there is a way to appeal the assessment, but that's a fool's errand as I'm well aware that if I do that my assessment could even increase as a result of any such appeal since I know what similar houses are selling for on my street and in my neighbourhood and my MPAC assessment is actually lower than what they are selling for. I appealed my assessment back in 2000 based on the price I bought it for in 1996, so it was easy to say, "this is what the house was worth on the open market at the time you did your assessment". At that time, they provide the hearing with a list of what other properties are selling for in order to justify their assessment. So now, it would not be a good idea to appeal (at least for me) as they will just pull out the list of what houses on my street are selling for.
