When people talk about "two-way" service, it usually refers to rush-hour service. And more generally, an idea that "when trains are running, they go both directions". GO only offers you trips inbound in the morning, an 8 hour gap, and then outbound in the afternoon. It's true that VIA offers some additional trip times, but they're scattershot, not intuitive, and they still don't meet the criteria of "trains in both directions at the same time".
