I visited this park for the first time over Labor Day weekend, 2004. The coasters are OK. The flats are insane, and the park itself it beautiful. Just beware of the border patrol......they tend to NOT believe that you are only visiting Canada to ride coasters. ;-) I got the third degree and then some, but they let me go after much questioning and searching. Ugh. I guess "Nope, no family or friends here, I just drove up from West Virginia to ride coasters in Canada" sets off a few red flags. It also didn't help that I was alone and had a rental car with with nothing in it but a black back pack. Go figure!
That, the insane prices, and the traffic was hell compared to the States. I guess it was worth a free ticket thanks to my Paramount season pass. :-)
