Alphabet subsidiary Sidewalk Labs will no longer pursue its dream of a smart neighborhood in Toronto.

In a Medium blog post, CEO Daniel Doctoroff said “unprecedented economic uncertainty” meant it was “too difficult” to achieve its dreams for Quayside, a proposed redevelopment on the city’s waterfront. If the company pushed forward with its vision — which was yet to receive sign-off from the Canadian government — “core parts of the plan” would need to be sacrificed, he said. “And so, after a great deal of deliberation, we concluded that it no longer made sense to proceed with the Quayside project,” Doctoroff added.
