  In this letter we present a model for quarks and leptons based on T7 as
flavour symmetry, predicting a canonical mass relation between charged leptons
and down-type quarks proposed earlier. Neutrino masses are generated through a
Type-I seesaw mechanism, with predicted correlations between the atmospheric
mixing angle and neutrino masses. Compatibility with oscillation results lead
to lower bounds for the lightest neutrino mass as well as for the neutrinoless
double beta decay rates, even for normal neutrino mass hierarchy.
