Cristian,I work a lot with Finance professionals and I can tell you that there is no shortage of accounting positions across the country. There really isn't one area better than another but probably the three best would be Toronto, Montreal and Vancouver. I have to say however that an accounting designation (CMA CGA or CA) will help very much. These designations are becoming, more and more, a requirement. Also, get a good understanding of Canadian and Provincial taxation laws. Canada is a very unique place and a thorough understanding of it's financial processes is mandatory.
In regards to becoming familiar with the job market here, the best and most efficient way is through the net. Check out Monster.ca and Canadiancareers.com and look through there website postings.
Hope this helps,
Harry
