Kenora Fire Chief Dave Pratt says crews were on the scene of their fourth house fire in the last week, early into the morning today.
A 911 call came from Argur Street around 11:30 last night, as the homeowners were woken up by their smoke alarms.
No injuries were reported and Chief Pratt says a full investigation will take place in the coming days.
This recent string of fires began overnight and early into the morning on May 22 with a house fire on River Drive.
On May 24, a home and a number of vehicles were lost on Highway 17 East.
And injuries officially remain unknown after a house fire on 18th Avenue North on May 26.
There was also a house fire on Hidden Trail just over a month ago, on April 27.
