Representatives of the consulate in Toronto and the Office for Science and Technology met with members of the Laurentian University School of Mines in Sudbury. The group then visited the SNOLAB laboratory, located below the Vale Creighton mine in northern Ontario.

The SNOLAB laboratory sits two kilometres underground in a former nickel mine in the Canadian Shield, in Sudbury. This laboratory was built to house a 12-metre sphere of heavy water designed to detect neutrinos produced by the sun. This heavy water allows scientists to trap the solar neutrinos, which disintegrate and produce light that is then detected by the 10,000 light sensors that line the sphere.

The 12-metre transparent sphere filled with heavy water and surrounded by a shell lined with photosensitive cells.

In 2002, experiments at SNOLAB (called ONS at the time) were able to confirm the proposed model for solar fusion. Neutrino studies have continued since then, and new experiments have been developed to study dark matter and the detection of supernovas.
