I want to know the answer to the following question:
On what date were CBC's remaining analogue transmitters shut down?
All the background I'm provided with is that "On July 31, 2012, at around 11:59 p.m. in each time zone, the remaining 620 analogue transmitters were shut down, leaving the network with 27 digital television transmitters across the country, and some transmitters operated by some affiliated stations.". Is that enough to answer the question?
Answer: yes
