Thanks!
That's a bit old now (predates selection of the Waterfront Shores bid by two years) but I can't find any other mention of the phase timing anywhere.
All I can find is that the developer is expecting to launch sales this year (the pandemic may affect that) and the registration web page notes they're still negotiating agreements with the city.
