Ottawa firefighters got more than lunch supplies when they stopped at a West Ottawa grocery store Saturday morning.

Ottawa Fire Services spokesperson Marc Messier says two firefighters were waiting in line after getting a few items inside a Robertson Road Loblaws around 10:30 a.m., when a man suddenly collapsed.

Messier says the pair started CPR immediately after realizing the man, who is in his 60s, didn’t have any vital signs.

Other firefighters in the truck outside of the store brought in a defibrillator and other equipment.

Messier says fire crews delivered two shocks with the defibrillator as part of their efforts to revive him, then gave another shock after paramedics arrived.

The third shock revived the man and he was conscious and speaking when firefighters left, according to Messier.

Ottawa paramedics say the man had suffered a heart attack and was in critical condition when he arrived at the Ottawa Heart Institute.
