The board says strong December sales volume helped make 2016 a record year for realtors in the Greater Toronto Area.
There were 5,338 sales transactions for all types of residential property last month including condo units and fully detached houses.
That was up 8.6 per cent compared with December 2015 despite a tight supply of properties for sale.
The board's MLS house price index, which adjusts for the different types of properties was up 21 per cent in December.
For the full year, TREB members had 113,133 sales through the MLS system up 11.8 per cent compared with 2015, which had the previous record high.
"A relatively strong regional economy, low unemployment and very low borrowing costs kept the demand for ownership housing strong in the GTA, as the region's population continued to grow in 2016,'' TREB president Larry Cerqua said in a statement Thursday.
The board says upward momentum on pricing accelerated as the year progressed and the overall average selling price for the calendar year was $729,922 up 17.3 per cent compared with 2015.
Another factor affecting prices was a constrained supply of active listings, which hit a 15-year low in December.
"Total new listings for 2016 were down by almost four per cent,'' said TREB's director of market analysis, Jason Mercer.
Mercer added that government rule changes and policy debates have focused on high demand but "what we really need is more policy focus on issues impacting the lack of homes available for sale.''
In October, the federal government made a number of changes aimed at stabilizing the country's real estate markets, including requiring stress tests for all insured mortgages.
The stress test change was intended to ensure that Canadians don't take on larger mortgages than they can handle, particularly in markets such as Toronto and Vancouver where affordability is stretched.
On Wednesday, the Real Estate Board of Greater Vancouver reported that home sales in Metro Vancouver, one of the country's most watched housing markets, fell 5.6 per cent last year.
Meanwhile, the composite benchmark price for all residential properties in Metro Vancouver, as measured by the Multiple Listing Service home price index, tumbled to $897,600 last month. That's down 17.8 per cent compared to December 2015.
