Yes you can and you should.. BUT
->It's not legal, with that being said, the only checkpoint you will have to pass is the airport immigration officer, this person you will have to be assured you are not there to seek employment or jobs at all. After that you're home free, but do avoid conflicts with anybody and law;
->Let's say you get a job there, you can:
a) start working illegally there if the company doesn't check for your papers and allows it (Don't do this unless you're desperate);
b) Now that you have you're job, you have to make sure the boss / the company is willing to write a LMO for you, this is a letter that states they need you as a worker there and no other Canadian citizen can fill that position;
Option B seems sweet... but The LMO takes time, has costs... that the person who is hiring you will have to endure... my advice for this, offer yourself to cover this costs, saying you would pay him/her/them the costs.
If option B was successful for you, be prepared now for the HARD part, the work permit application:
1st - Leave Canada because this process is going to take several months;
2nd - Start working on you're application, gather all the documents they ask for, you probably will have to translate some documents into English, this has to be done at an official translator;
3rd -Wait...Wait...Wait...
4th - Work Permit DENIED/ACCEPTED, if denied they will tell you what you were missing or what you did wrong, if accepted you're good to go. I believe you will get a paper that says you're work permit has been accepted, however the work permit itself you will only get it at the arrival in the airport in Canada.
Wish you good luck friend, and if you need more help try and provide more information about yourself like education, age, job you're seeking, etc.
