Shaw Communications is moving to buy Mountain Cablevision, adding one of the country’s last family-owned cablecos to its holdings.

The deal stands to pass some 41,000 cable customers, 28,000 Internet subscribers and 27,000 telephone customers currently with the Hamilton, ON-based company to the Alberta giant. The purchase, made via a Shaw affiliate, is subject to approval by the CRTC and the Toronto Stock Exchange.

The move extends the reach of Shaw across southern Ontario, the backyard of its Toronto-based competitor Rogers Communications.

The value of the deal has not been disclosed. Further details are expected pending the approvals.
