In Canada it varies. Dentists are terrible and always covered by private insurance. In BC pharmacare is capped out-of-pocket by the province but it's a high cap so you will generally have employer insurance just like you have in the US - while as Ontario has full prescription coverage.

Oh the same thing goes for vision insurance, alternative medicine (RMTs and acupuncture) and some medical devices - i.e. a CPAP for Sleep Apnea.
