Bell on Wednesday will become the second Canadian carrier to formally launch an LTE-based 4G (link active soon) service. Going live first in the Golden Triangle area in and around Toronto, the service will echo the same 75Mbps peak, 12Mbps to 25Mbps real-world speeds seen on Rogers. Bell's edge will be its support for 42Mbps HSPA+ as a 'fallback' with Rogers' service at a more modest 21Mbps.
