Two plus two equals four, the sky is blue, and rent is getting more expensive in Toronto.

The average rental price for a one bedroom apartment in the city finally cracked the $2,000 mark this month, according to data from Padmapper.

Last month, the apartment hunting website listed the median cost of a one bedroom unit in Toronto at $1,850.

That's an increase of just over 5 per cent, according to site's real time rent trends table. More unsettling still is that we saw the median price of a one bedroom hit $1,500 only nine months ago.

Toronto is quickly closing in on Vancouver as the most expensive city for rent in Canada, though the latter city remained even less affordable as of last month.
