They're set to speak along the waterfront starting at 2:30 p.m. ET.
In March, Waterfront Toronto, which was created by the three levels of government to oversee transformation of waterfront land, announced it was seeking a "funding and innovation" partner to create a complete community along the water near Bonnycastle Street and Queen's Quay East.
Andrew Hilton, director of communications and public engagement at Waterfront Toronto, described it as "a kind of test bed: a place in the city where we can look at trying new approaches, new technologies."
At the time, reports indicated Sidewalk Labs, a subsidiary of Google parent company Alphabet Inc., had thrown its hat into the ring.
