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.
Conservatives hate that their money is taken away to fund poor people and take money away from their rich friends, and it brings them to defund healthcare, liberals hate that it creates a natural monopoly and their inability to see a functioning society work without private hospitals brings them to defund healthcare
There's no point pretending you know what people's motivations are. Conservatives I've read/heard seem to generally want similar outcomes, but disagree drastically on the methods.
