I want to know the answer to the following question:
When was CBC's anologue upgrade extension set to expire?
All the background I'm provided with is that "In mid-August 2011, the CRTC granted the CBC an extension, until August 31, 2012, to continue operating its analogue transmitters in markets subject to the August 31, 2011 transition deadline.". Is that enough to answer the question?
Answer: yes
