  The SNO+ experiment is a large-scale, multipurpose neutrino experiment
situated 2 km underground at SNOLAB in Canada. Successor to the Sudbury
Neutrino Observatory, the SNO+ detector has inherited much of the original
infrastructure including the 12-m diameter acrylic vessel which serves as the
main detector body. Initially filled with ultrapure water, the SNO+ experiment
has completed operations as a water Cherenkov detector, having set new limits
on multiple invisible nucleon decay modes, performed measurements on
$^8\mathrm{B}$ solar neutrinos, and made the first observation of reactor
antineutrinos in pure water. The detector medium has now been replaced with
liquid scintillator, and a new physics programme is being pursued including
measurements of solar neutrinos and $\Delta\mathrm{m}^2_{12}$ from reactor
antineutrinos. The liquid scintillator will be doped with >4 tonnes of
$^{\mathrm{nat}}\mathrm{Te}$ to enable a search for neutrinoless double beta
decay.
