For instance, be aware of this Canadian telecom, as well: A smaller entity also with turnaround potential The other Canadian telecom stock that was sold off sharply is TELUS Corporation (USA) (NYSE:TU). Here, too, the broad sell-off seems a bit unwarranted and the stock may have upside for a three to five year investor.

TELUS Corporation (USA) (NYSE:TU) is experiencing several of the same positive and negative trends as BCE Inc. (USA) (NYSE:BCE).

However, its net access line total, including residential and business lines, is trending 5% lower year-over-year. TELUS Corporation (USA) (NYSE:TU) is focused on rolling out 4G LTE next-generation services.

If not for the burden of the deteriorating wireline business, TELUS Corporation (USA) (NYSE:TU), like BCE Inc. (USA) (NYSE:BCE), would be a growth story. This brings us to the third and final Canadian telecom: A strong player in wireless and cable Finally, Rogers Communications Inc. (USA) (NYSE:RCI) is primarily a wireless services provider. It is also a major cable TV and Internet services company. Rogers has 34% and 31% share of these two markets, respectively. The company stands out among the three Canadian telecoms due to its growing revenue and earnings from its two key segments. But it too could not avoid a steep sell-off of its stock earlier this year.
