At Toronto City Council’s November 8, 2016 meeting, they voted to adopt a 47 ward system (toronto.ca)  where previously there were 44 wards. Some last-minute refinements were implemented to keep some neighbourhoods together (for example, Regent Park would have been part of two separate wards). The changes will mean that ward sizes are more uniform – between 51,850 and 70,150 people by 2026 and will likely be in place for the 2018 election. The approved changes are subject to appeal to the Ontario Municipal Board (OMB).

We are part of Ward 28 today, but in the approved 47-ward redrawing, we will be part of the Revised Ward 23 as seen in the image below:
