I've had my iPad 3 on Bell LTE since May, and it's been pretty fast when I'm in an LTE area (unfortunately, I have no LTE coverage at home or at work). 25-30 Mbps was common.
My new iPhone is on Virgin, which should be the same network. I haven't seen more than 15 mbps on the iPhone though. I haven't had the iPad and iPhone with me at the same time to compare. Perhaps it's just that the network is getting more loaded than it was earlier in summer. 3G is pretty darn fast though, often getting close to 10 mbps, whic is pretty good in itself.
