OTTAWA -- Two cats died in an apartment fire in Ottawa's Pineview neighbourhood Thursday afternoon, one of three fires firefighters responded to in a span of three hours.

Just before 5 p.m., Ottawa Fire received a 911 call from a resident reporting a kitchen fire on Appleton Drive, between Meadowbrook Road and Beaverpond Drive.

The kitchen fire was located in a unit on the fourth floor of the four storey residential building.

The fire damage was limited to the unit. One person has been displaced.

At 7:25 p.m., firefighters responded to multiple 911 calls for smoke in a high-rise unit on McLeod Street at Cartier Street.

Firefighters were able to quickly extinguish the fire in a seventh floor unit, and rescued a pet dog from the unit. The dog was reunited with its owner outside the building.

One person was treated by paramedics on scene and transported to hospital.

The cause of the fire remains under investigation.

Firefighters then responded to a call from a resident reporting smoke coming from a single-storey detached bungalow on Avenue U off Tremblay Road.

Ottawa Fire says the fire started in the kitchen, blew through a window and extended to an attached carport.

No one was hurt.
