this should explain the name changes, basically they can not use the paramount names anymore hence why they had to change.

On 14 May 2006, it was announced that Cedar Fair Entertainment Co. was interested in acquiring the five Paramount theme parks, including Canada's Wonderland. The acquisition was completed on 30 June 2006.[4] As a result, in early January 2007, Cedar Fair began to drop the "Paramount" name from all of their former Paramount parks, and the park is currently referred to once again by its original name, "Canada's Wonderland". The 2007 season marked a transition year of removing "all things Paramount" throughout the park. By the start of the 2008 season, the Paramount logo and similar references will be removed.

In August 2007, Cedar Fair announced that Fearfest would be renamed Halloween Haunt to remain consistent with other Cedar Fair parks. At this time Cedar Fair also announced that Spooktacular would be discontinued. In place of Spooktacular, the park extended its regular operating season until the last weekend in October. Thus, the park is open to the public during the day, and Halloween Haunt runs in the late evenings on October weekends. The park also announced its addition for 2008, a new hypercoaster called Behemoth, which will be the largest roller coaster in Canada, and will open in May 2008.[5] Behemoth will also be the tallest ride in the park, reaching three feet taller than the park's ride Drop Zone
