Azeris laugh only if there is a real reason to laugh, smiling too widely for no apparent reason could create a "gap" between Azeris and Canadians.
Azeris are serious people, likely due to their history.
You should not bring up the subject of politics yourself, because you never know whether a person is for or against the current government establishment.
For your first meeting, make sure you dress sharply looking like a successful Westerner since after all, their image of a Canadian or someone from the West is based on what they see in the movies, the news or papers and magazines.
In the future, when you have met everyone and are on a first name basis - which takes time - you could relax your dress to work and social events.
You could stand close to the people you are talking to, since Azeris are very social people, unless it is the opposite sex.
When talking to the opposite sex, make sure you are as formal as possible, leaving no impression that there are other reasons beyond work for this show of interest.
