High Quality Content by WIKIPEDIA articles! Behemoth is a steel roller coaster at Canada`s Wonderland in Vaughan, Ontario, Canada. It is a Hyper Coaster designed and developed by Swiss manufacturer, Bolliger Mabillard. Behemoth is currently the tallest and fastest roller coaster in Canada. However, in 2012, Leviathan, also manufactured by Bolliger Mabillard, will be built at the opposite end of Canada`s Wonderland "stripping" Behemoth`s tallest and fastest titles. The ride is similar to Diamondback (Kings Island), Goliath (La Ronde) and Nitro (Six Flags Great Adventure).
