Video – Ottawa’s big boom…

Ottawa’s Sir John Carling Building is brought down by explosive demolition.

Advanced Explosive Demolition (AED) has imploded the former home of Agriculture Canada.

The biggest blast in Ottawa’s history was over in seconds on Sunday, reducing the 11-storey John Carling Building to 40,000 tonnes of rubble by 420 kilograms of explosives.

Hundreds of people gathered 300 metres away from the federal office tower at 930 Carling Ave. that overlooked Dow’s Lake to catch a glimpse of the $4.8 million demolition.
