I had the same concern before I first moved to Edmonton, but I think that you'll be surprised at just how diverse the city is. I don't think it would be fair to ever compare Edmonton to London (I presume the city in the UK , not the one in Ontario) or even Toronto because they're very differently-sized cities and have very distinct histories. Eastern and Central European settlers were largely targeted during early colonization efforts and those origins are definitely apparent today, but the population is much more diverse than that. There are many opportunities to explore the various cultures present within the city and the food scene is surprisingly strong given that the city is often (undeservingly) overlooked. Some of the more prominent events include the Heritage Festival in early August and Cariwest, but there are many smaller events that celebrate other facets of the community. On a day-to-day basis, the greatest diversity in one location is probably in the Whyte Ave/university and downtown areas, but you can find enclaves of different backgrounds around the city.
