If you're in any situation to adopt/foster you can help and even if you can't you can donate money to the organizations mentioned in General section to help the Ontario pit bulls. After the ban passed, rescuers have 90 to get the Ontario dogs either (1) in a rescue out of Ontario, (2) into foster homes, or (3) adopted. After the 90 days, all pit bulls in shelters will be euthanized or sold for research. I would look in threads in General if you want to donate money or look in the Rescue section if you can adopt/foster.
Oh yeah, welcome to the board, it's a great place.
