STI does stand for Sabby's Transport. I have dealt with them a long time.
STI is owned by the father, Mak -- his sons, Sabby and Raj worked there for a long time. In late 2021 (?) Sabby went out on his own and started Sabby's Transport. At that time Sabby was still working out of the STI office in Delta. Raj also departed STI but I dont know where he is now.
I might have some of the details wrong on what happened as I'm just looking from the outside in but STI Transport Inc. and Sabby's Transport Incorporated are two different companies.
I have the issue with Sabby, not STI
STI does not do long haul that I'm aware of and I use them for WA / BC lanes and some local, I will agree with LrgCar's comments on STI being good people.
For me, STI was Sabby and Raj so it is easy to mix up the two companies and I tried to support Sabby in his new company.
