It's been a busy long weekend for fire crews in the capital.

They've responded to at least seven fires since Friday -- causing more than a million dollars in damage and displacing over a dozen people.

Early Monday morning, a fire sparked at 840 Kinsmere Avenue at 9:15 a.m.

Alana McBride, a neighbour, noticed the smoke and stopped to see if anyone was home. When she opened the door a pet dog escaped.

“I just kind of ran up and grabbed him, brought him across the street, gave me some oxygen made sure he was ok,” said McBride.

No one else was in the home at the time. A women and her 6-year-old son lived in the home.

The fire is believed to have started in the kitchen. The exact cause is still under investigation.

Total damages to the home is $300,000 to the building and $100,000 in its contents.

On Sunday, more than 60 Ottawa firefighters tackled a blaze in the city's south end. They were called just before 10pm to a row of townhouses on Ashpark Crescent.

“We were just having a few drinks on the patio enjoying Canada day. Called a cab. Went to go see the fireworks. Then we get a call from the landlord saying the house burnt down,” said Allison Mulvale.

The fire was contained to 2 units. However, nine people were displaced.

Ottawa Fire investigator says blaze caused by a discarded cigarette butt.

01:03:28-:42 “They were smoking. One of them had stamped out a small fire that started from a cigarette but unfortunately after they left it was not stamped out properly.” said Dave Montone of the Ottawa Fire Services.

No one was hurt, but we're told damage is extensive.

And on Sunday afternoon, four people were left homeless after a west Ottawa house fire.

Emergency crews were called to 141 Withrow Avenue near Algonquin College just after 1 p.m., reporting heavy smoke coming from the second floor.

Firefighters upgraded it to a third alarm when they found zero visibility inside and flames coming out of the roof.

Ottawaparamedics said the 45-year-old homeowner was treated for smoke inhalation after he tried to put out the fire. They said he didn’t want to be taken to hospital.

Fire crews said four people that lived in the home won't be able to return, with $450,000 damage to the building and $250,000 damage to its contents.
