Safety is indirectly compromised in Canada by the high operating costs forced on domestic airlines by the tax and fee evironment created by the government.
YYZ is the most expensive airport in the world to operate out of. Ottawa still collects airport rent even after selling them and privatizing their operation. Nav Canada exists as a non profit organization, but enjoys a legislated monopoly. Security tax. Fuel tax. GST. There is so little money left over for profit, that airlines develop "efficiencies" that compromise safety in the name of savings. Normalization of deviance. The industry is in a pot of hot water, where the temperature is raised by one degree every month. At what point do we realize we're boiling?
To me, there is still a very strong safety culture at the operational level in Canada; the shop floor, the flight deck, ops, ATC etc. But overall if each department compromises best practices by just slightly, this affect overall system safety in the negative in a meaningful way.
Taxes, landing fees, and airport rent HAVE to come down!
