The number of sales also shot up 16 per cent, when compared to the first quarter of 2015. However, new listings this March were down when compared to the same time last year, adding more fuel to the red-hot market.
"I think that speaks to the strength of the market across the board," Mercer told CTV News Channel on Tuesday. In general, real estate properties are selling at slightly above their asking prices, which indicates strong price growth in the market, he said.
"That is representative of a market where there is quite a bit of competition between buyers," Mercer said. However, he downplayed individual reports of outrageous bidding wars for the city's most-wanted properties, saying they are "not necessarily representative of the norm."
Mercer said many first-time homebuyers are turning their attention toward Toronto's supply of condo apartments, instead of going for a more expensive detached home.
"The condominium apartment is remaining a popular option, and in fact receiving an increase in sales over time," he said.
On Monday, Vancouver's housing market also continued its record-breaking trend, with March statistics showing it was the highest-selling month ever recorded.
The Real Estate Board of Greater Vancouver reported the average price of a detached home at $1.34 million, up 27.4 per cent over the same time last year. Overall price growth surged by 23.3 per cent since last March. Property sales in March were also up 24 per cent over February
