Algoma Taxicab Management Ltd. v. M.N.R., 2006 DTC 2497, 2006 TCC 71 -- summary under Subsection 5(1)

The taxpayer, a taxicab driver, was found to be self-employed given that the rental fee he paid for the use of the taxicab could range between 62% and 70% depending upon factors which were mostly under his control and the revenues he generated could be significantly increased by demonstrating initiative, he ran the risk of loss through credit card fare charge-backs or NSF cheques and his taxicab operation was not highly integrated with that of the taxicab lessor given that he was free to work whenever he wished and for as long or as short a shift as he wished, and could take time during those shifts to do personal errands.
