A fire on Wilson Road Friday afternoon in Welland caused $500,000 damage, said Welland Fire and Emergency Services Chief Brian Kennedy.

Kennedy said firefighters were called to 223 Wilson Rd. at 6:03 p.m. and upon arrival found a fully-involved garage fire.

"It started in the garage and extended into the house and a back outbuilding," the chief said, describing the outbuilding as a pool house.

He said homes on either side of 223 Wilson experience heat damage from the fire.

There were 34 fulltime and career firefighters on scene, and the fire service activated call back to have off-duty firefighters come in and man the stations in case of another call in the city.

Kennedy said the Ontario Fire Marshal's Office was contacted but did not attend the scene.

The Fire Marshal's Office is called in when damage is more than $500,000 to a structure or there is a serious injury or death.

No one was injured in the blaze, though one volunteer firefighter was checked at the scene by Niagara Emergency Medical Services paramedics for a possible heat-related issue.

"We had a rehab unit in," said Kennedy, as daytime temperatures were in the 30s.

He said the family will be out of their home for quite some time.

Welland's fire prevention officers investigated the cause of the blaze and Kennedy said they believe it to be accidental in nature due to an electrical issue.
