Update:
After collecting the names of 'MWD' companies from this thread, I sent resumes online in the preceding 3 weeks but none of them replied. Stupid HR people. So I had to call and convince the receptionists to give me the MWD guy's email address/number. The larger companies refused or didn't know, so screw them. The smaller companies are more willing to let me speak to their MWD people. So after speaking to their MWD guys, they would usually say they are not hiring at the moment or come back in Fall.
Since landing in Calgary earlier this week, I have taken the H2S Alive course and knocked on the doors of 20 'MWD' companies. I have been using the Wicked Hostel as the base and launching expeditions to the far corners of the city.
On Thursday I managed to cover most of the companies in the South East with some progress. Even the companies that were initially saying they were not hiring when I called them up from Toronto were now enthusiastically taking my resume when I showed up at their doorstep. Oh yea, I made sure to remember the receptionists' names, so I address them with a sense of familiarity. They were now giving me a timeframe of when I will be hearing from them (usually by the following week).
On Friday, I showed up to most of the smaller directional companies in downtown. One of them didnt have operations in Canada, so they were ready to hire me as an MWD hand in S.America ! I said I will think about it and proceeded to apply in person to a few more. I didnt want to go overseas yet.
In the afternoon, I got a call from another small MWD company that he wants to meet me within the next hour. He sat down and basically wrote down all the good points: Single, young male, no wives, gfs, technical background, team player, safety tickets and the bad points: no long term work permit (goddamn, I should have noticed the fine print on my off-campus work permit

, he wasnt too bothered about it tho), no rig experience.
He was concerned only with my lack of rig experience. He was rightfully worried about letting me anywhere near those expensive tools without training. He was ready to hire me as a shop hand doing the manual work like fixing tools, etc to get an idea of what I am dealing with before sending me out to the rigs as a full-time MWD.
He was saying they dont have the manpower to train me as much as the bigger companies do!
He said the second (better) option was for me to work for the larger ones like Schlum, Halli or Weatherford for a few months, get trained with the tools and come back to him.
He recommended the second option as he is need of more experienced hands.
I was toying with the idea of quitting grad school if I got a job ( I am halfway through it). But now completing it is the only option as it will give me a 2-year graduate work permit without resorting to the much-maligned TFW visa + make me standout with the larger companies.
Since I have already covered I am still gonna give the smaller companies in Eton a shot on Monday, to see if they will sponsor someone for TFW . Otherwise I am treating this week as a reconnaissance mission for next year.
So for anyone trying to be an MWD, here is a breakdown of steps:
Have a valid work permit,
Read Atlantic's MWD thread,
collect company names,
apply online
call their operations office (not the corporate HQ)
say you have applied online but no response yet,
ask the MWD guy's contact,
Call him/email him resume,
Fly to Calgary/Edmonton,
Stay in Wicked Hostel/HI,
Buy/Rent a truck,
Dress smartly, show up in person to hand resumes in Sep/Oct (Aug is too early

)
When called in to discuss position:
Explain that you are Single, have/willing to buy a truck, team player (football, hockey,etc), emphasize any technical degree/diploma/computer familiarity, not worried about working long hours.
