Hi Guys there is certain thing that you have to know in the history of AT and why they may prefer peoples speaking both languages
First AT was started by about 10 ex Quebecair pilots who were french Canadians and some of those had try before to join AC or Wardair, or CP
But in those time 1970/1980 even AC had only about 10% of french Canadian
I remember one day even myself I received an answer from Wardair that they had more suitable candidate. Yes at that time they were hiring some pilots with Cessna 310 time and I was only a Convair 580 captain ......
So this is why those pilots, when they decided to start AT they said it will be a Cie for the French Canadian because they were not welcome in the others aviation Cie
I d ont know if it is the same thing now in Canada because me I left a long time ago
