The general anti-avoidance rule in section 245 of the Income Tax Act is essentially an interpretive rule.

In the recent GAAR Consultation paper, the Finance expressed concern over the unified approach and considered codifying the “scheme” approach in Copthorne to give more weight to “abuse of the Act read as whole.”
