I will be coming to the GTA to help my Dad while he is undergoing chemo treatment at PMH downtown in the next 5 weeks. I have 2 questions:

1: When I arrive at the airport (YYZ) he says the up train to union station is the fastest way to get downtown. From union station what train/subway do I connect to to get to hospital or can I walk from union station? 2: Ill be staying in Brampton and commuting most days into the city to visit him instead of driving. What is my best go stations or rout to get downtown from Brampton? I am comfortable traveling by transit once I know the best routes and types (subway/bus/train ect) Thanks for your help
