CD,
You took the "post" right out of my mouth. Many aviation professionals in Canada are oblivious to the channels they can use to address safety concerns.
rvm,
Canada has one of the safest civil aviation systems in the world, no doubt mainly because we have one of the best civil aviation regulators in the world. There are good and bad individuals, but on the whole TC does it's job (and addresses its mandate) quite well.
Canada's civil aviation system is unsafe? I agree it can be. But I think the blame more often fails on the operator. Not the regulator.
Want examples? Its too easy. Just read some TSB reports.
