Heh, or in the case of Global, they probably think they're wasting money by broadcasting a free OTA signal! ;)

Just watch: this'll be the next trick used by Canadian broadcasters -- probably Global will randomly start claiming equipment failures with their existing analog OTA transmitters, and do next to nothing to attempt to repair them, yet gladly continue supplying/leasing their signal to BDUs like Rogers, Star Choice, and Bell ExpressVu, in a sneaky attempt to add fodder to their whiny arguments that maintaining an OTA transmission plant is too expensive.

Makes me wonder... if a conventional OTA Canadian broadcaster 'quietly' just turned off their OTA transmitter(s), would the CRTC/Industry Canada even notice or care?
It's too bad TV has evolved its distribution ways from beyond the heyday of cable TV -- cable companies used to have to pickup signals from antennas like anyone else, but then broadcasters started providing direct links to cable headends via fibre, making their OTA transmitters a very limited part of a broadcaster's viewing audience.
