MONTREAL - Transport Canada has grounded a Quebec-based charter aviation company, effectively ending its air operations.

The agency revoked Aeropro's operating permit this weekend following an audit that found repeated violations of Canadian aviation regulations.

Aeropro is a 22-year-old company that runs business and recreational charters.

It says it has 250 employees based out of the Quebec City airport.

The move by Transport Canada comes on the heels of an Aeropro plane crash near the airport last June that killed seven people.

An Aeropro spokesman says the company was disappointed by the court's decision and takes passenger safety seriously.
