  We present the system size and flavour dependence of the chemical freeze-out
temperature ($T_\mathrm{ch}$) at vanishing baryo-chemical potential calculated
via thermal fits to experimental yields for several multiplicity classes in pp,
pPb and PbPb collisions measured by ALICE. Using the Thermal-FIST Hadron
Resonance Gas model package, we compare the quality of fits across various
treatments of strangeness conservation under different freeze-out conditions as
a function of the charged particle multiplicity density $\big \langle
dN_\mathrm{ch}/d\eta \big \rangle$. Additionally, we examine how the
anti-hadron to pion yield ratios of light and strange baryons, as well as the
$\phi$ meson, evolve within a flavour-dependent model. Through a unique
two-temperature chemical freeze-out approach, we show that flavour dependence
of $T_\mathrm{ch}$ in a Strangeness Canonical Ensemble leads to a natural
explanation of strangeness enhancement from small to large systems at LHC
energies without requiring any non-equilibrium particle production at small
$\big \langle dN_\mathrm{ch}/d\eta \big \rangle$.
