Kenora's fire chief is dispelling rumours that four house fires in the past month are connected.

Dave Pratt says the causes of most of the fires have been determined.

"They are all different in nature in terms of the origin, but they are all explainable," states Pratt.

"The concern in the community about arsonist is going around and setting these fires, I just want say, that's not true and they are all isolated incidents."

Pratt says the cause of three of the four house fires has been determined, and they are not connected.

"The fire on Augur Street was electrical in nature.  The one fire up on Hidden Trail we believe was started by unattended cooking and then there was one on Longbow Lake we believe was started by an indoor fireplace."

Pratt adds that the Ontario Fire Marshall has concluded it's investigation into a fatal house fire on 18th Avenue North, but they are still waiting for the final report.
