So far, three companies have come forward about doing routes.
AV Transit is going to do a route running between Saskatoon, Martensville, and Warman. This one looks like it was probably being planned long before the shutdown of STC was announced.
In addition, a transport company is looking at doing a run between Yorkton and Regina
Finally, a limo company.
There have been a number of protests, rallies, and letter writing campaigns to try to save STC, but I fear it is in vain. If STC is doomed, I'm hoping for Greyhound or Red Arrow to setup a run between Saskatoon and Regina relatively quickly.
