Bill C-8 Proposed New Trademark Defintion

Bill C-8 which addresses improved proposals for anti-counterfeiting also includes a proposal which will potentially widen the definition of trade-marks to include taste, texture, a number, a letter, etc... I wonder if the folks at McDonald's are trying to define the taste of a Big Mac. How is Coke going to define its beverages? Trade-mark law is going to get a whole lot more fun!
