Don't buy any tools until you have found a job! We hired a G3 from Ontario who moved here because of the downturn in your economy. 4 of his classmates couldn't find local work either. If you get a job slowly start buying the basic tools.
Don't rush out and buy all the most expensive Fluke tools. I use generic brands like MA Line, UEI, and they survive -40 in Wpg. You need a good multitester that can read microamps and test capacitors and check amperage. A true RMS meter is a good choice. You need a manometer. A complete set of Craftsman screwdrivers. Canadian Tire sells reasonably good 8" to 18" pipe wrenches and they go on sale a lot. Unless you use them as a installer daily you won't wear them out. A 3-5 gallon Shopvac is useful. Hacksaw, files, Klein wirestrippers and crimpers. Wiss sheet metal aviation snips/CTire and a good 14.4v Makita cordless drill and flashlight. WWG Totaline is a good place to buy tools and develop a rapport with the staff, and they have sales flyers. Don't buy Sears monstrous big 18 volt drill as it won't fit in tight places and is tiring to use. Buy the "Fundamentals of Gas Utilization" textbook by John Dutton (college bookstore or order it from Chapters) and learn everything in it.
Good Luck
