What is the difference between VIA Rail's Business and Business plus classes? VIA Rail is now offering to classes in business class, Business and Business Plus. I cannot find anywhere on the VIA website a description of the difference between the services being offered.
The fare comparison page at Via Rail has the information you need. There is no difference in the onboard experience (nor the at-station experience such as using the lounge) at all. The only difference is in the flexibility of the fare - change fees and cancellation fees.
You can see the same pattern with Economy and Economy Plus - same onboard experience, less change fees etc for the Plus.
