Transport Canada would be inviting even more attention to their own disgraceful F&DT regulations if they denied any company access on that basis alone. Fatigue is a word that doesn't have much meaning to them despite the occasional lip service.
Banana, brave words about growing a set and declining flights at EK if you are tired. If you work there and do so regularly I suspect you wouldn't work there much longer, and focusing the blame on individuals deflects it from where it belongs on the systemic problem. Face it, Dubai is what it is today thanks to well documented but conveniently ignored slave labour. EK has no qualms about moving the goal posts back at their discretion to make the system work. They are chronically short of crews now, and have orders in to double their fleet. I agree with nolimit, they are a crater in the making.
