1. go to PCC and get adresses for companies
2. Apply over email, most folks like this now, as faxes can be expensive
3. Fax those that aren't online
4. call about a week later and politely ask if they received the resume, use your name so it sticks in their minds, be polite, ask if they mind if you drop in and say hello, oh and be polite
5. plan a road trip the main aviation hubs are smithers, calgary/edmonton, yellowknife, saskatoon, winnipeg, thunder bay, toronto, montreal, and iqaluit.
6. pack everything you need for a summer in march, go on road trip, and be prepared to start right away "very rare, but happens".
7. call every 2-3 weeks after your trip
best of luck.
