Floor protection requirements for uncertified stoves can be complicated, therefore it's best to contact your local certified chimney sweep for details.

Clearance Requirements for Uncertified Wood Stoves
An uncertified wood burning stove has not been tested, and certified by an accredited lab under ULC-S627. As such, the following clearance to combustibles are required in Canada. Please check your local Authority Having Jurisdiction (AHJ) to determine if an uncertified stove is permitted to be installed in your area.
Clearance to combustible requirements for non certified radiant wood stove is 1200 mm (48"). A stove with a metal jacket casing requires 900 mm (36"). Wood stoves certified for installation in an alcove may not be reduced, unless otherwise stated by the appliance manufacturer or AHJ.
Wood Stove Change Out Rebate
Uncertified wood burning stoves are generally inefficient, and contribute to poor air quality. There are wood stove change out programs that offer rebates when an uncertified stove is changed out for a new efficient wood burning stove with low emmisions. The CVRD is a municipality on Vancouver Island, British Columbia, Canada that offers rebates.
