The applicant union sought judicial review of an Ontario Labour Relations Board decision granting a certification application by OPSEU for newly hired paramedics.
The applicant argued the paramedics were already bound by its existing collective agreement with the municipality.
The OLRB relied on extrinsic evidence to find the collective agreement's scope clause did not automatically include the paramedics.
The Divisional Court quashed the OLRB's decision, holding that the scope clause was unambiguous and the OLRB's reliance on extrinsic evidence to interpret it was patently unreasonable.
