Hi Tanor
I'm originally from the UK and moved to Melbourne five years ago. I came over on a working holiday visa, transferred after 3 months on to a 457 visa, got employee sponsored for PR and then applied for Citizenship, which has just come through.
I love it here and I have a few Canadian friends who do too!
From my experience, the visa issue will be your biggest hurdle. Not saying it is impossible, just that it will be tricky. I had an excellent employment record and work in an industry that is starved of local talent and it still took me 7 months of constant applying to get a job over here.
I used a few recruiters but was also applying to companies directly and it was one of the direct applications that resulted in me landing a job. I had a lot of skype interviews with people basically saying if I had PR and was already in the country, they would offer me a job but as it was they would have to look into the logistics of sponsorship (because there are a number of requirements companies have to satisfy).
In the end I had to commit to moving here without a job to show people that I was serious. Luckily I was under 31 when I moved, so I was eligible for a working holiday visa. My company employed me on probation for 3 months, and then transferred me to a 457 visa once I had worked for 3 months and they knew I was a good hire. It's been smooth sailing since then, but it was a leap of faith to commit to Australia, sell all my stuff, rent out my apartment in London and fund my own move here.
Other people have other stories - I know a couple of Canadian teachers here that got job offers easily. Are you under 31 or under? Would you consider coming here on a working holiday visa? I don't know really anything about your industry so can't advise you there but check out the skilled occupation list to see if your job title or others like it appear:

The good news it the list gets updated based on skills shortages. Look at previous versions of the list online and see if your profession appeared - if it's not on there currently but was previously on there, chances are, it will make an appearance again.
Good luck - it's a great country.. basically hot Canada!
