I don't see the need for a Canadian Standard drive system. Of course, I don't see the need for different plugs for the same voltage/current in the British Isles, mainland Europe, and the U.S.. (I do, however, see self-serving, proprietary, profit-seeking reasons)
I think the star-drive system (Torx) encompasses any advantages that square-drive fasteners have over Posidrive, and certainly Phillips or other U.S. standards. I think the star-drive is superior to the square-drive in holding the fastener and transmitting torque. I also think that it has already dramatically won the global contest for superiority in function and population.
Phillips fasteners are designed to "cam out" so you can't hardly break a quality fastener.
If you want to be able to deliver unlimited torque in a small diameter to a fastener, you don't need a Canadian-centric fastener. Internal hex heads are the long-time standard on multiple continents.
Star-drives were developed, I think, to improve the torque transfer in a smaller diameter. They also had a side benefit of holding a fastener on the end of a driver in free air. That makes a lot of assembly operations more efficient.
I may be missing something but I designed a lot of different machines/processes for a long time and I have studied these things before. I'm always open to learn more, however.
