Park Place (Barrie) by The Go Transit

[NiftyScent]

So I'm looking at the go transit site and I am overwhelmed. I looking at the Go schedules/train stations/bus stations/routes that will get me to Park Place on Saturday August 11 (Im taking my little cousin to a concert). The show starts at 11 a.m. I am confused on how the Go works and what routes/buses I will have to take to get me there.

This is my first time going on the Go. Please help me!

Edit: By the way, I live in Scarborough!
