Webasto Ontario runs at 78% of its industry's injury rate - safer than the typical Electricity and electrical signal measuring instruments manufacturing workplace, earning a grade B.

Webasto Ontario: 2.6 TCR = 78% of Electricity and electrical signal measuring instruments manufacturing BLS 3.3 · 2y Form 300A (see methodology below)

Webasto Ontario safety composite

Webasto Ontario scores strongest on dart rate (safer than 68% of same-industry peers) and weakest on total case rate (tcr) (safer than 14%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
