...but probably if your profession falls under the 38 list, I think chances are good. These must be the vacant professions in the job market that no Canadians and landed immigrants can fill.
The concern here is if your profession is regulated in Canada, meaning a license is needed before you can practice. Employers are searching for licensed or at least eligible applicants for registration before they will hire you. And so far, in my research, it's Manitoba nursing regulation body only who allows prospect applicants to start registration process before the applicants land in Canada. For many, if not the rest of regulated professions, you need to be a landed immigrant or a Canadian citizen before you can start your registration process.
Chances of a job offer is higher if you will search job in a "not so immigrant destination provinces" than major provinces like Ontario, BC, Alberta, where 90 percent of landed immigrants reside and probably 90 percent of the new 250,000 immigrants who are landing this year (2009) plan to settle.
These are not my experiences, they are just my opinions based on my research.
