Market Rental Rates (Q4/07) from the document:
$84 Midtown Manhattan
$44 Lower Manhattan
$35 Boston / Calgary / Washington
$27 Toronto
$25 Los Angeles
$22 Denver
$20 Houston
$19 Ottawa
$15 Minneapolis
I would call it a mid-range rental rate for Toronto office space (note: I do not know if these numbers have been normalised for location, floor, etc.) and if you leave aside Manhattan, it's near the top end of rental rates.
