Considering the distance between Quebec and Toronto, it would be better to think about how to minimize travel time by raising maximum speed or building high speed line. That's because conversational trains are not rapider than vehicles, and then won't be competitive.
Without speedup, high frequency plan will result in vain. Only if speedup is done, the corridor will get more passengers so as to need higher frequency.
