In the US you would have to put Drywall or something similar on the wall to the house as a fire barrier.

Use drywall under the OSB for the wall connected to the house.

In Ontario you must use drywall on the wall that attaches to the house but, as Rosco mentions, there is nothing to stop you from covering it with osb to match the rest of the garage.

Us code states a one hour fire rating between home and garage.
5/8 sheet rock does this and it has to be taped also
or you could use this..

One-Sided One-Hour Fire-Rated Wall Assemblies
In late 1997, Underwriters Laboratories Inc. (U.L.) promulgated a new fire-rated wall design that recognizes both oriented strand board (OSB) and plywood panels for wall sheathing in one-hour, fire-rated, load-bearing exterior wall assemblies.
New fire-rated wall design - U.L. Design U356
One-sided assembly, rated for fire from the interior face of the wall
7/16-inch or thicker plywood or OSB sheathing, installed vertically or horizontally on exterior face of wall (joints must be blocked when panels are installed horizontally)
Studs spaced 16 inches on center
Code-approved exterior finish
Glass fiber insulation (R-13 minimum) or mineral wool insulation; minimum 3-½ inches thick
5/8-inch Type X gypsum wallboard on interior face of wall
Fire-rated walls which are rated only from the interior face are permitted under the 1996 National Building Code and the 1997 Standard Building Code when there is more than five feet of horizontal fire separation distance.
