According to a teeny blurb in this week's issue of The Grid, Bell Canada is looking for permission to start charging a dollar for a pay phone call, up 100% from the current cost of 50 cents. "Bell says the money will pay for upgrades to the GTA's 22,000 payphones."
Does this mean they want to save them? Likely the opposite. The increased cost may drive usage down giving Bell more reason to get rid of them.
