in most other industries where you apply for a job far away from home, you will still need to make the treck to wherever that position is, but the employer will have contacted you in response to a resume.
Dunno about that- outside of aviation, I've sent an awful lot of resume's out for various positions, but the only time I ended up with a decent job out of it is when I rocked up and asked to have a chat with the boss. An emailed resume' is an easy thing to ignore, as it doesn't show a whole lot of initiative.
And anyway- hundreds of foreign backpackers make the trip up north each year just for fun, so whats the big deal about doing a trip up there looking for work?
