Oceana Canada asked them to each collect samples from a list of target fish — from either grocery stores or restaurants of their choosing — using DNA testing kits from the LifeScanner lab in Guelph, Ontario. The volunteers submitted the samples along with details
about their purchases. Their results closely mirrored the Oceana Canada findings presented earlier in this report. (Note that citizen-sourced results were not included in the national or city-by-city results.)
