Read the CRTC letter - it is not taking new evidence or submissions; ergo, this is not a case of competitors trying to derail Mobilicity.
The government, the the Throne Speech, promised to allow increased foreign ownership but has provided no further details. Implementation of any changes would take months and require the approval of the House of Commons and Senate. Mobilicity should have launched long before this would happen.
My reading of the CRTC letter is that this is merely a pro-forma review it is required to undertake before the licence is issued. The only surprise to me is that it hasn't been completed, but then Wind was ready to launch less than 2 weeks after the government gave the go-ahead, so it may not mean a lot.
