On the Pearson website there is a connecting guide. Enter your arrival and departure information and it gives you a step by step guide on what you have to do.

Note that the train is currently out of service until the end of October and shuttle buses are running between terminals.
Thanks for the URL,
laidback71. That is where I got the info in the first place.
Technically, am I clearing Canadian Customs by reclaiming/dropping off the bags? It is sounding a lot like transiting in the US.
It looks like the bus should take me about 15 to 20 minutes max to go from T1 to T3. Any estimate on how much time it takes to get out of T1 and then to clear security in T3??
