The story so far

Comparing the original population and employment forecasts with the 2011 census

The 2001-2031 growth forecasts in the Growth Plan were developed in 2005 using information from 2001 census figures[1] (taken a few months before the economic downturn that followed the events of September 11, 2001), since the 2006 census figures were unavailable when the Plan was prepared. Now that 2011 census figures are available, it is possible to compare the first forecast period in the Plan with actual growth experienced by municipalities. Table 3.1 shows the results of this comparison.

1 Greater Golden Horseshoe Growth Forecasts to 2041, Technical Report, November 2012, Hemson Consulting Ltd.
2 Growth Plan for the Greater Golden Horseshoe, 2006, Office Consolidation, January 2012, Ontario Ministry of Infrastructure.
Note: 2011 Population and 2011 Growth Plan Population Forecasts include an undercount, which adjusts the population to account for people who were not enumerated.

Table 3.1 indicates that in 2011 the total population of the GGH was only slightly less than the level predicted by the growth forecasts, but the location of the total population varied considerably, in some cases by as much as 10%. In the Inner Ring, the forecasts underestimated growth in York and Peel Regions and overestimated growth in the City of Toronto and Durham Region. In the Outer Ring, the most notable discrepancy is that for Barrie, which in 2011 had 16,000 fewer people than the forecast had predicted.

A more revealing method of assessing the accuracy of the Growth Plan forecast, however, is to compare the amount of growth experienced with the amount of growth forecast, rather than comparing the total population forecast with the actual total population.

Table 3.2 compares the actual amount of growth as recorded in census counts to the forecast amount of population growth in the Growth Plan. The results are revealing. The differences in growth are much greater compared with the differences in total population shown in Table 3.1. For example, the City of Brantford had a difference of -5% when comparing total population but a -75% difference when compared to the forecast growth, and the City of Toronto 1% versus -21%. More than half of municipalities in the GGH missed their growth forecast by +/- 25%. The County of Haldimand missed the growth forecast by -100%, the City of Peterborough exceeded its forecast by 60%.

The differences between the actual growth and forecast growth are more notable in the Outer Ring compared with the Inner Ring. The Region of Waterloo had the most accurate growth forecast in the Outer Ring, exceeding the forecast by only 3%.

Note: 2011 Population and 2001 and 2011 Growth Plan Population Forecasts include an undercount, which adjusts the population to account for people who were not enumerated.

The amount of growth allocated to each lower-tier is at the discretion of the upper-tier municipalities, and different upper tiers have taken different approaches to this allocation exercise. Appendix D shows the allocation of growth by all upper-tier municipalities to all lower-tier municipalities. Figure 3.1 shows the allocation of growth for three regional municipalities: Waterloo, Halton, and Peel.

Figure 3.1: Allocation of population growth by upper-tier municipalities to lower-tier municipalities: Waterloo, Halton, and Peel Regions, 2001-2031

In Waterloo and Peel Regions, most growth is allocated to historically urbanized areas. In Halton, by comparison, growth allocated to the well-established communities of Oakville and Burlington is far surpassed by that allocated to the town of Milton (its population is planned to increase by 600%). This growth allocation in Halton Region does not appear to reflect the goals of the Growth Plan, since it requires the creation of new infrastructure to serve the additional population in Milton, rather than making more effective use of infrastructure available in the already urbanized areas of Oakville and Burlington.

The Environmental Commissioner of Ontario has noted that the "Growth Plan allows growth and intensification to take place in watersheds where communities are already struggling with water supply and wastewater treatment issues. These communities will eventually require major upgrades to their water and wastewater infrastructure to accommodate the projected population growth."[2] Such upgrades would perpetuate the problems identified in the introduction to the Growth Plan. "New infrastructure is being built to service lower-density areas, while existing infrastructure in the older parts of our communities remains underutilized."[3] The Growth Plan was developed to prevent this unnecessary expansion of infrastructure.

In 2013, Growth Plan Amendment no. 2 removed the original 2001-2031 growth forecasts of the Growth Plan released in 2006 and replaced them with forecasts for the 2031-2041 period. The new forecasts also included transitional forecasts, which acknowledge the original 2031 forecasts adopted by municipalities over the past seven years through conformity amendments.

It remains to be seen what will happen at the time of the 10-year review of the Growth Plan. As the Environmental Commissioner of Ontario notes, "It is unclear whether the GGH Plan will allow for radical reductions in growth allocations if major shortcomings in water and wastewater servicing emerge in communities targeted for growth."[4]
