YMQ: all airports are designated by 3 letters. Canadian airports all -with vey few execptions start with the letter Y; YYZ is Toronto's Lester B. Pearson, YVR is Vancouver's and so on. Montreal, where I live have 2 international airports: YUL (Dorval) and YMX(Mirabel). When you look in an airlines timetable, they often refer to Montreal by using YMQ (Y/Montreal/Quebec). You would also see, for example, Moscou referred to by the letters MOW when the actual airprort code is SVO(Sheremetevo). That's for the YMQ.
Now about what do you do to become a pilot. I am not really qualified to answer that one. But, since there are a couple of pilots on this forum, I am sure one of them will be kind enough to give you all the information you need. For instance, there is Purdue Cadet who is in the process of learning to become a pilot. There is one thing i can tell you, though. It takes a couple of years to get through the whole project. But if you really want to become pilot -and you have to think about this first- the time spent learning will be worthwhile.
