Searching for low mass dark matter particles at SNOLAB

90 years after its first evidence by F Zwicky, the nature of the dark matter of the Universe  is still unknown. There is a consensus it should be made of elementary particles but their search has been going on for several decades without success. Huge progress in sensitivity has been done, though,  thanks to new innovative detection techniques. Indeed some new techniques allow to enlarge the exploration of parameter space.  I will describe status of two projects I have developed, within international collaborations, thanks to a CERC grant in Canada, to be installed at SNOLAB, the Canadian underground laboratory. These two projects will allow to search for dark matter particles down to masses of about 0.1 GeV, one based on the use of spherical gas detectors, NEWS-G,  the other one involving cryogenic detectors, CUTE and SuperCDMS.
