TOSI and “the provision of services”

In Kathryn Walker, “The Services Carve-Out from TOSI” Canadian Tax Focus 4:4 (May 2018), the author considers the meaning of business income from the “provision of services” in the definition of excluded shares in s 120.4(1). She notes that the Income Tax Act uses the phrase in only a few other places and provides no guidance on its meaning. The few cases that refer to the phrase do not provide any guidance either. The author speculates about the meaning to be ascribed to the phrase and concludes that “[t]his review of what “provision of services” might mean shows that large sections of the economy could be vulnerable to the new TOSI.”
