  DEAP-3600 is the largest running dark matter detector filled with liquid
argon, set at SNOLAB, in Sudbury, Canada, 2 km underground. The experiment
holds the most stringent exclusion limit in argon for WIMPs above 20 GeV/c$^2$.
In the most recent published analysis, the background events due to
alpha-induced scintillation in the neck of the detector limited the
sensitivity. The sensitivity of the detector in the next WIMP search will be
improved thanks to the decrease in backgrounds achieved by hardware upgrades
and applying multivariate analyses. Moreover, the WIMP analysis has been
revisited in terms of a non-relativistic effective field theory framework, and
the impact of possible substructures in the galactic dark matter halo was
explored. This analysis was motivated by the latest results from Gaia and the
Sloan Sky Digital Survey. Here DEAP-3600 set the world's best exclusion limit
for xenon-phobic dark matter scenarios. Finally, a custom-developed analysis
has recently pointed out the extraordinary sensitivity to ultra-heavy,
multi-scattering dark matter candidates, resulting in world-leading exclusion
limits on two composite dark matter candidates up to Planck scale masses. These
proceedings, after a quick overview of the dark matter detection in DEAP-3600,
outline the detector upgrades and the dark matter search results from the
collaboration of the last three years.
