Ok, I called both company that you posted. The one Wei posted is more expansive and further, it is $96+GST+$2, which is $104.86. it located one and half hour away west from Ottawa.
The one 聂 小 倩 posted is cheaper and closer, it is $85 + 7% + $2, which is $93.09. It located one hour away from Ottawa, close to Bryson, Que. This price included 2 nights camping, 1 hot lunch and ofcoz Rafting. The tent is $15/one if you need rent from them, the manager will give us for $10 + GST at discount price. However, they don't anything available until July 13 and 14th.
So, what do you guys think?
