Start for some reason can't/won't offer the same packages Rogers can.
I guess I'll just go with Start. 1Mpbs is still faster than 600kbps, and I hope they'll offer faster options in the future.
Short version: Start will be able to offer those speeds. It's just a question of how soon, and if the prices will stay the same. Neither can be answered until we hear the results of a CRTC decision, which we should have in a few weeks.
