Image of the physical model of Tower 2 (The middle tower - that I believe will be the first one to go up) with the Concord Pacific VP Peter Webbb, standing nearby in the model shop.

I believe they're scheduled go to Public Hearing for this project phase in Early January or February 2021 according to the City of Burnaby's projects page (which was just recently updated), and construction should start not too long after that.
(P.S. the model in the background looks to be one of Telford on the Walk by a different developer (Intercorp) that's slated for the lot just behind the Sun Towers projects on Beresford between Telford and Sussex on the south side of the mall and Skytrain line.
I could be wrong, but I'd put good money on it.)
