A new international science laboratory, SNOLAB, has recently begun operation 2 km underground at the site of the Sudbury Neutrino Observatory (SNO), near Sudbury, Canada. The laboratory incorporates the SNO detector and includes several new experimental areas with a total excavated volume about three times larger than the original SNO cavity. The SNO detector has now completed operation with heavy water and data analysis is being completed with improved accuracy by combining all three phases of the project. A new project, SNO+, has recently been funded and will provide high sensitivity for neutrino-less double beta decay, low energy solar neutrinos, geoneutrinos, supernovae and other physics measurements. A number of dark matter measurements are in progress or preparing for deployment and a new supernova measurement, HALO is also being deployed. The status and physics objectives of the experimental program is outlined.
