600+ of Canada's 800+ emergency departments publish no wait time information at all. In Saskatchewan, as far as I can tell, not one of 76 does.
None in Newfoundland either.

What we need for modeling already exists in most emergency department information systems.

Count of triaged patients not yet seen by a physician
Minutes since arrival of the longest-waiting one.

Those are the two terms of a queue. How long the line is, and how old the head of it is. With those numbers we can model queue drain rate. Physicians on shift sharpens it further, if your scheduling system allows for it.

A scheduled CSV or JSON at a URL every few minutes is great. A charge nurse typing three numbers into a form two or three times a shift also works.

These are not huge asks, and none of it is patient data. No names, no diagnoses, no identifiers. A count and a clock.

Quebec already publishes the count for all 119 hospitals on its public dashboard, and about two dozen Ontario hospitals already publish the longest wait.

A hospital doesn't need an entirely new vendor or system to deal with this. ERstat is offering to work out the models for free.

We publish our error rate beside it. This is early work and we will get things wrong, which is exactly why the accuracy is public.

@raghu_venugopal Thanks for the mention! The site is https://t.co/BwiYzMopkx for those interested. I'm not sure if er-watch uses any of our data.

Work in a Canadian ER?

Three numbers a shift turns your hospital's ERstat estimate into a measured one: patients waiting, longest current wait, physicians on.

20 seconds from your phone. Free, no app, no password, no patient data.

The official ER wait times tool has been unavailable since the One Person One Record rollout began May 9. That's 16 days without an official estimate. ERstat's prediction model is currently the only source for NS emergency room wait time estimates. https://t.co/6B8RVo6GLA #nspoli

For anyone heading to a Canadian ER this weekend: live wait times at https://t.co/6B8RVo6GLA. Saturday evenings into Sunday mornings tend to be the busiest windows across most hospitals. A pharmacist or walk-in is often faster for non-urgent conditions.

@raghu_venugopal @CAEP_Docs Thanks Raghu, this means a lot. ERstat aggregates ~200 hospitals' live public data and predicts the ~400 silent ones. You named the real gap: ER docs see live waits on EMR, but public views lag. Closing that distance is what's next. ER doc feedback always welcome. @CAEP_Docs

@MatrixMysteries This is exactly why we're building https://t.co/6B8RVo6GLA a free tool to check ER wait times before you go. We track 200+ hospitals live so far and working to add more. 587 Canadian ERs still publish nothing. That needs to change. People need to know wait times and alternatives.

Newfoundland has collected ER data since 2011. It shares none of it with the public. Doesn't even report to CIHI. 0 of 24 hospitals publish wait times while rural ERs run on Virtual ER with no in-person doctor most of the week. https://t.co/yNQZPqmUL0 @CBCMarkQuinn @CBCNL #nlpoli

643 ER closures in 18 months (Nov 2023–May 2025). The SHA tracks them in real time internally — but won't share it publicly. Full breakdown: https://t.co/WdH1Knx8jn @jaredclarkeNDP @AlexanderQuon @Sask_NDP #skpoli

Built something I think Canada needed. One place to check real-time ER wait times across the country. 700+ hospitals, free, no sign-up.
