Putting a lot of your eggs in one basket is not a good financial strategy !

Is hubbing a lot of your flights through one station YYZ ,a good stategy?

Yesterday, we saw the impact of a force majeure event at YYZ. The airport was completely shut down.

In fact any major weather disruption in YYZ causes AC major headaches.

Hence the question: Is AC too dependant on YYZ as a hub?

The introduction of the Embraers and the 705 will take some of the pressure from YYZ with the introduction of point to point direct flights bypassing YYZ.
