Current PhD candidate at Western. I can answer any questions you may have (or anyone else with Western-specific questions, since our interview day is Friday). A Skype interview will just be a proxy for what you would have discussed on interview day. You get to skip all the other various interviews with us *wonderful* people, so that can be a benefit. But Skype interviews are more impersonal, so I'd be sure to make extra effort to appear engaged. Honestly, missing the social is nbd. People are usually exhausted from the day and those of us who've participated in interviewing are kind of wanting to get on with our days tbh so it's not like it's a critical evaluation. You do get a nice rundown of the program at the day, as well as a chance to speak candidly with current students, so if it comes down to making a decision between Western and another school that can also be a weakness of not attending.
