I guess most are displayed. One particular station that I know is not displayed is Wx 71882. It also does not show up in nearest weather station.
Thanks for the the screenshot I missed that feature and it's very helpful.

How can I display weather stations on the map?

I tried using reported temperature and reported wind, but I only see one bubble in southern british columbia. I know there are many more stations in the area.

Otherwise, is there a way to find the weather stations near a location I am checking the forecast for?
