UNIONS-3500 weak lensing data yields S_8 = 0.831^{+0.067}_{-0.078} in flat LCDM from 2D cosmic shear, consistent with Planck within 1 sigma.
UNIONS r-band data constrains S8 to 0.891^{+0.057}_{-0.084} via 2D harmonic-space cosmic shear, consistent with Planck at 0.79 sigma after modeling baryonic feedback and intrinsic alignments.
