Heh. That’s not setting the bar very high. How about: Engineering starts with the letter “E”. There’s some useful information for ya.
Just kidding.
I’m not familiar with Canadian schools, so I’m afraid I can’t give you much feedback there. However, like KenGr said, nearly all freshman (and much of the sophomore) courses required are identical among the disciplines, so your choice now could easily be changed later without losing any credits. Also, many universities offer a one- or two-credit freshman level “Introduction to Engineering” course, the purpose of which is to help students like you decide which discipline they’re most interested in. Check out the course listings at McGill & UBC to see if something like that’s offered.
To choose a discipline, figure out what you like to do. Like taking apart radios and putting together compters? Try electrical. Like fixing bikes or cars? Try mechanical. Like the concept of working on BIG projects like dams? Try civil. Interested in the way plastics or carbon fibers are made? Try materials. And so forth.
My own perspective: I’m a mechanical engineer, because I like to work on things that move, and that I can pick up. Electrical? I can’t see the electrons moving around. Booooring. Materials? So you make a lump of stuff. Ho hum. Chemical? So you make a bottle full of stuff. Still ho hum. Civil? Big things, that’s cool, but so big that there’s no pride of ownership. Ah well. Mechanical? Now there you can make a widget and have it do things, and carry it around and show people. That’s fun. YMMV, of course.
As far as salary, I’d hesitate to make a choice based on that. However, here’s a couple suggestions, if you want numbers. First, most universities perform a salary survey of recent graduates. Ask to see this (they use it for recruiting, anyway). Second, check out the 2002 salary survey from the Professional Engineers and Geoscientists of British Columbia (this is a pdf file). Average salary for recent graduates is about $45000 (Table 9). Unfortunately they don’t break out recent graduates by discipline, but you can infer from Table 13, using the “lower decile” numbers (average LD salary = $44000) that mechanical starting salary is about $45000, civil is about $43000, and electrical is all the way up at $63000. I’d caution you that these numbers might be highly variable as supply and demand changes, though.
