It's more likely to affect speeds within your network.
Ordering a faster Telus package will be best to improve speeds. You really notice if you share your internet with others in the home and at least one of you like to stream videos. BTW, make sure your wifi security like WPA2 is enabled. I've seen performance issues because people did not secure their wifi... they were offering free internet to the neighborhood where people were hogging up all the bandwidth.
