Well, I liked how candid he was in answering. I did not detect any bad intentions either; he was just frank. It was just normal for him to not bother speaking french in Montréal. And it sure reflects the thinking of most that works at AC's HQ. (I actually know a few)
What I find most interesting is Mr Rousseau's comment that you could perfectly live and work for 14 years in Montréal - without speaking any words in french.
Somehow when reading anglo medias here, I was under the impression that Quebec's anglos were oppressed, persecuted, could not be served in english and what not. Some even used words like "ethnic cleansing".

We all knew this rhetoric was all pure BS. But anglo medias just kept repeating it.
Quebec bashing sells newspapers / readership it seems.
Now Mr Rousseau just comfirmed how welcoming Montréal actually is to anglos.
(Kudo to Mr Rousseau for this reality check).
FWIW, in my 35 years of service in the federal public service (including 13 in the Cdn Forces), I often had bosses simillar to Mr Rousseau. They somehow were holding positions designated as bilangual - but could not really speak any words in french.
But we were not offended as we understood that we (francos) were the one that had to be actually bilangual, not the other way around - even in Quebec...
(Were we ever submitted back then).
I thought things had improved a bit in Montreal - but not so, it seems.
Anyways, that won't change my flying habits.
I appreciate all those non-stop destinations AC offers from Montreal.
