I was able to secure a job without status (not in IT) but it is possible. With the job I was able to secure a workpermit, subsequent PR under provincial nomination and finally my citizenship.
Relying on job boards and just regular old job hunting approaches will fail. You will have to take a much more direct approach, be willing to do all kinds of things that will cost money with the risk of no return (like travel to canada for interviews). You will have to clear answers on many complex questions, like how and when and what.
Many people try to get jobs without PR status so employers tend to view these with some suspicion as most just end up wasting time.
It is not easy but it is possible. I got a job in two months after I started hunting, and was able to come to Canada within 6 months after I started the process, took about another year to get PR and after that the rest is history.
This is a complicated process, and will be very challenging, and you may not even succeed. Few do. If you want to do this you have to be certain that this is what you want. It will require unwavering resolve to make it happen, otherwise... well.
Good luck
