As of now Telus is not enforcing monthly caps but I suppose that can change as more and more people start streaming from Netflix and other channels. They would need to have a way to monitor usage online and to date I don't see that. Any serious streaming would require at least Internet 25 as according to the Telus website Internet 15 only gives you 100 hours of web content and three hours a day isn't much if you watch Netflix a lot. The caps are way too low and since they are jacking up rates continuously far exceeding the inflation rate they should at least provide larger caps. Don't count on it though as Telecom companies are as greedy as the Banks and Oil Companies.
