Pickering nuclear power plant in context
By gross operating capacity Pickering nuclear power plant is the 3rd largest of 4 operating nuclear sites in Canada, holding 16% of the country's operating capacity, and ranks 79th of 172 worldwide.
Its operating units started up between 1983 and 1986; the median unit is 41.5 years old, older than the median of 41.0 in Canada.
The 8 units with both construction and grid dates on record took 4.4 to 9.4 years (median 6.6) from construction start to grid connection; the median across all reactors connected in the 1980s is 7.3 years.
The nearest other tracked nuclear sites are Darlington nuclear power plant (28 km), Darlington New nuclear power plant (30 km) and Robert Emmett Ginna nuclear power plant (154 km).

| Robert Emmett Ginna nuclear power plant | United States | 154 km | 0.6 |
How these are worked out: ranks use gross operating capacity; ages count from the start-up year on record, as on the age page; build times run from construction start to grid connection, as on the build-times page; ratings are the tracker's net and design net capacity, as on the uprates page. Distances are straight-line between exact positions, so a site with only an approximate position gets none. A unit missing a date or a rating is left out of the figure that needs it.

| Location | Pickering, Ontario, Canada |
|---|---|
| Coordinates | 43.8107, -79.0689 |

Elevation is read at the listed coordinates from a 30 m terrain model (SRTM 30 m). Two independent models differ by a median of 6 m across our plants and by up to about 40 m on steep or coastal ground, and a point on a shoreline can read as sea level. Distance to the water is measured to a generalised 1:10 million coastline, so a few kilometres or less is not resolved. This is context, not a design-basis or flood-risk figure.
