Two homes were destroyed after a blaze in northwest Edmonton.
Fire crews were alerted to the blaze at 84 Street and 173 Avenue just before 1 a.m. Sunday.
Captain Joe Koreman said a passerby stopped after they noticed sparks in the area.
“A passerby had noticed sparks in the area, drove into the cul-de-sac and noticed one of the houses were on fire,” he explained.
“They immediately called 9-1-1 and then started banging on doors to alert the residents.”
About 30 fire fighters responded to the scene.
District fire chief Lorne Corbett told CTV News one of those fire fighters sustained a sprained ankle during the incident.
Corbett also said both homes suffered heavy damage.
“The first units on scene they encountered heavy flames at the rear of the residence, the original house, that spread to the house to the south.
“It originated, we think, on the rear deck of the house that was involved in the beginning.”
Koreman said two other homes also suffered exposure damage.
Officials said the damage was estimated at $900,000.
Investigators are still working to determine a cause.
