It sounds like you’re referring to the Basin Media Hub that was recently announced. That project is overseen by CreateTO and the City of Toronto.
The Basin Media Hub was identified as part of a larger cluster of production, interactive and creative uses in the Port Lands Planning Framework, which was approved by City Council in 2017. The planning framework sets a 50+ year vision for the Port Lands which includes existing industrial uses, new media and screen-based uses as well as mixed use residential communities. The planning framework also includes recommendations for how these various uses will develop compatibly over time. One of these new mixed-use residential neighbourhoods is Villiers Island – which is created by our Port Lands Flood Protection project. Our plan for Villiers Island is that it will be a climate positive neighbourhood, which means that in addition to reducing on-site emissions, the neighbourhood will help lower emissions from elsewhere in the city too. Villiers Island will also include over 1,000 new affordable homes. Just east of Villiers Island and directly north of the Media Hub is McCleary District, which will be another mixed-use residential neighbourhood once a more detailed precinct planning process is undertaken in the near future.
