The plot of land YTZ sits on was formerly an amusement park similar to that of early Cedar Point in Sandusky, OH, which is currently home to many of the most popular high-intensity roller coasters in the world.
Perhaps it can be converted into an amusement park that can rival that of Six Flags Canada's Wonderland, especially given the news that Wonderland's parent company Cedar Fair merged with Six Flags with the merged company being called Six Flags.
This new amusement park can have what Six Flags Canada's Wonderland currently doesn't have: an Intamin roller coaster and an RMC roller coaster.
Centreville can be for families with young children, while this new amusement park would be for thrill-seekers with many high-intensity roller coasters. It would provide much-needed competition given that there are not many amusement parks within a reasonable drive from Toronto that have multiple high-intensity rollers without the need to cross an international border aside from Canada's Wonderland. Cedar Point happens to be the next nearest amusement park aside from Canada's Wonderland to have multiple high-intensity roller coasters.
