  We present an analysis of data on light flavour hadron production as function
of event multiplicity at LHC energies measured by the ALICE collaboration. The
strangeness-canonical approach within the framework of the THERMUS statistical
hadronisation model is used for a simultaneous description of pp, p-Pb, and
Pb-Pb collisions. The rapidity window dependence of the strangeness correlation
volume is addressed and a value of $\Delta y = 1.33 \pm 0.28$ is found. With
the exception of the $\phi$-meson, an excellent description of the experimental
data is found.
