It seems a bit strange to call out the Conservatives specifically. Ontario has been purposefully underfunding healthcare for decades upon decades, with most of the damage done decades ago. Peterson (Liberal) forced practitioners to operate under fixed rates defined by the province, which even lead to a doctors strike. Rae (NDP) eliminated 8,000 acute care beds. Harris (PC) eliminated another 6,000 beds.
Governments of the last 20 years have held the status quo, which leaves them equally culpable.
