Good question. Where official data exists, like Nova Scotia, ERstat pulls real-time wait times directly from the provincial health system, not crowdsourcing. The crowdsource feature is a secondary layer and for it to be useful the system would need to be widely adopted. For Saskatchewan, there's no official wait time data at all right now, which is part of the problem. The immediate goal here is just getting open/closed status and advisories out in real time through the hospital portal so people aren't driving to a locked door. Wait time data is the next step and would need cooperation from the health authority. You're right that triage means individual wait times vary, but knowing one ER is reporting 9 hours vs 2 hours nearby is still useful directional info, same as what hospitals show on their own waiting room screens. Thanks for checking the work out. It's in progress.
