Visualizing Infrastructure Project Distribution and Budgets in Ontario: A Heatmap Approach

Diving Into Ontario's Infrastructure Development: A Comprehensive Visualization of Project Distribution and Budget Allocation


Ontario, the most populous province in Canada, is home to a diverse array of infrastructure projects. However, the distribution of these projects and their budgets are not uniform across the province. To illustrate these geographical disparities, we created two heatmaps using project data from the Ontario's Government Open Data Portal.

Creating the Heatmaps

The heatmaps were created using latitude and longitude data for each project. Each cell's color intensity represents either the number of projects or the total budget in that area. This type of visualization, known as a hexbin plot, is especially useful for large datasets, as it prevents overplotting and makes patterns easier to discern.

What the Heatmaps Show

The first heatmap visualizes the number of infrastructure projects in Ontario. The darker areas, primarily located in the southern part of the province, indicate a higher concentration of projects. This aligns with expectations given the higher population density and economic activity in Southern Ontario, which includes major urban centers like Toronto and Ottawa.

The second heatmap represents the total budget allocated to projects across Ontario. This visualization illustrates not just where projects are located, but also where more financial resources are being allocated. Interestingly, while Southern Ontario still appears darker, some areas in the North also show substantial budget allocations, suggesting the presence of fewer but more costly projects.

Limitations and Next Steps

While these heatmaps offer valuable insights, it's important to note some limitations. Firstly, the geographic division into northern and southern regions is a simplification and may not perfectly represent the actual geographic characteristics of Ontario.

Secondly, the heatmaps do not account for the size or complexity of the projects.

Despite these limitations, the heatmaps serve as a useful starting point for understanding the geographical distribution and budget allocation of infrastructure projects in Ontario. Future research could delve deeper into the factors influencing this distribution and explore ways to promote more equitable infrastructure development across the province.


Visualizations like these heatmaps are a powerful tool for making sense of large datasets and revealing patterns that might otherwise go unnoticed. As we continue to monitor and analyze infrastructure projects in Ontario, we hope to uncover more insights that can inform policy decisions and contribute to the province's growth and prosperity.
