Approximate percentage overlay of Toronto municipal wards from 44 to 47 model

 

The table below describes the relationship between the existing 44 wards and the new 47 wards, and estimates the overlap between those that share the most area. These percentages are rounded and do not account for any change or geographic feature smaller than 0.01 sq. km.

The geographic form of seven wards (1, 2, 6, 10, 11, 35 and 33) did not change, but the identifying numbers for two of them (33 and 35) did change.

Guide to reading the chart

This chart shows the degree of overlap between the existing wards and the new wards.

For example, the existing Ward 4 (A) is 100 percent within the boundaries of the new Ward 4 (B). However, because the new ward is larger than the existing Ward 4, the percentage of the new ward that is comprised of the existing ward is 83 percent.

Existing Ward Number (A) New ward (B) that most overlays with existing ward (A) % of existing ward area (A) covered by new ward (B) % of new ward area (B) comprised of existing ward area (A)
4 4 100% 83%

 

Figure 1 - A diagram showing both the boundary outlines for Existing Ward 4 (A) and New Ward 4 (B) overlaid on top of each other. The diagram demonstrates that while 100% of Existing Ward 4 (A) fits inside New Ward 4 (B), the expanded New Ward 4 (B) contains additional geographic areas not previously covered by Existing Ward 4 (A). As such, it is calculated that New Ward 4 (B) is comprised of 83% of Existing Ward 4 (A).
Figure 1 – Existing Ward 4 (A) is 100% within the boundaries of new Ward 4 (B). However, as new Ward 4 (B) is now larger than the previous existing Ward 4 (A), the percentage of the new ward that is comprised of the existing ward is 83%.
