One consideration in BC is whether you worked on the Employer's Premises or not.

My wife had an IT support contract where they told her to come in to the office to monitor the monthly billing runs, and for to bill time for a goofy team building session. Korkin Commission happened, and she was told not to bother coming in any more for those, to make her a bona fide contractor. 

Several Indendent Contractors I worked with were told to take their Korbin Employee offers or be terminated. They all said No Thanks. Years later they were still there but subcontacting through IBM Global as part of IBM's BC Subcontracting Quota.
