It's in service now, but limited to educational institutions and big business.
Our national network Ca*Net3 just joined up as part of the international Internet2 network. It has multiple OC-192 streams (~40 GBps), making it the fastest national network in the world.
Our government announced last week that Ca*Net4 is in the works, and donated $110,000,000 towards building it. This network will be 8 times as fast as the old one, with total throughput of around 320GBps.
