The blaze broke out around 11:00 last night and Kenora fire crews spent all night trying to bring the fire under control.
Fire fighers are still at the scene mopping up, and there is still some smoke that can be seen coming from the roof of the building.
A spokesperson for the fire department says the apartment building was pretty much engulfed in flames by the time they arrived at the scene.
All the occupants managed to escape the burning building and there were no injuries reported.
The cause of the blaze is still under investigation
