For every 1,000 housing units, property taxes generate approximately $5 million. So that is roughly the cost for national defence.
However, the cost of the infrastructure required to build these housing units must also be taken into account. It is necessary to ensure that there is infrastructure to provide drinking water and to treat waste water. Then, it's necessary to ensure that there are roads.
These, too, represent major investments. We're talking about several tens of millions of dollars in municipal investment. Developers are also needed to ensure the construction of the 5,000 housing units planned for that portion of the land, the former Saint‑Maurice firing range.
