Telus is a full-fledged member of the oligopoly of mainstream providers in Canada. They easily could, but have strong interest in not doing so to protect their profit margins. I don't agree with it, but I don't blame them.
All these big internet companies only care about capital. Capitalists run the business. Like many people said that they can very easily offer Unlimited. I mean look, Bell is offering it for only $10 a month while all this time are the ISP are saying how much it costs them and plus with there stupid excuses for not offering unlimited.
Teksavvy just does what these big companies don't which is offer unlimited. If Teksavvy can all these providers can.
