It was back in 2009 when the United States had full powered TV stations make the switch from analog broadcasts to digital for over the air viewers. (The transition for low powered stations will occur in 2015.) Our friends north of the border in Canada who rely on over the air reception for TV will be facing their own digital transition (in most markets) by the end of August. One of the markets is London with several stations (with a few already converted to digital) that may make it across the lake for those who have or will rescan their converter boxes or digital TVs’ with their outdoor antennas aimed north. The complete list is here at http://www.user.dccnet.com/jonleblanc/Canada_TV_Stations/ON.html for you to explore.
