Just in time for Hockey Playoffs, the CBC has announced that its Over-The-Air digital television transmitters in Calgary and Edmonton will officially launch on April 1st.

The new high definition stations will also be available on Shaw Cable in the two Alberta Centres and will arrive on Telus TV on May 27th.

"With Calgary and Edmonton as Canada's third and fourth largest English TV markets respectively, we're really pleased to be adding these important members to Canada's CBC HD family," said Alan Dark of CBC.

While the official launch is tomorrow, Digital Home readers in Edmonton have reported to us that CBXT-DT in Edmonton was on the air on digital channel 5.1 sometime early this afternoon while our readers were still searching for CBRT-DT in Calgary to begin broadcasting.
