The verdict

Ontario - Mazda runs at 59% of its industry's injury rate - safer than the typical Transportation workplace, earning a grade B.

Ontario - Mazda: 2.7 TCR = 59% of Transportation BLS 4.5 · 3y Form 300A (see methodology below)

Ontario - Mazda safety composite

Ontario - Mazda scores strongest on total case rate (tcr) (safer than 75% of same-industry peers) and weakest on fatalities (safer than 51%), 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).
