I received the following email from Robert Deluce which provides a detailed explanation for the new proposal. Note that Porter will happily accept either the 168 Metre or 200 Metre option but that the later offers advantages for all stakeholders.
Also notice the below graphics showing the 168M vs 200M proposal. The differences between the two proposals are so negligible (I can't see any difference).

To Porter Plans supporters:
Porter has sent the City of Toronto a letter validating our initial runway design in support of the plan to operate Bombardier CS100 aircraft from Billy Bishop Toronto City Airport (BBTCA). A second design was also submitted.
Specifically, the proposed extension of 168 metres into the water at each end of the main runway meets the city’s request to not result in “an extension of the Marine Exclusion Zone as currently configured, that would materially encroach upon the western channel shipping channel.”
Over the past several months, Porter has worked closely with stakeholders and our airport consultant, LPS Avia Consulting. The runway extension requires only an immaterial lateral movement of certain buoys that does not affect boating access along the Western Channel.
Porter is also proposing a second runway design option for the city to consider. This includes an additional 32 metres into the water on each end of the main runway, for a total of 200 metres, and provides a number of additional benefits compared to the 168 metre option, including:
Favourable positioning of the existing Marine Exclusion Zone buoys, continuing to ensure no effect to the boating community by not materially encroaching upon the Western Channel.
Additional take-off runway distance allows for improved noise abatement procedures, including using less power on take-off.
A slightly longer runway should enhance the Western Channel’s safety and navigability for vessels by providing a breakwater for wave protection and reducing sediment build-up in the area.
Both runway options will work for the CS100. We will be happy if the city selects either one, so that we can begin offering flights to new destinations across North America.
