Here are two very important sites to have on hand.
Toronto Wildlife Center: Here is a organization that takes in Injured wildlife from all over. The Humane Society that I work for, we work with them closely. If wildlife can be rehabbed, we drive them up to TWC. They also have a wildlife hotline, if you have concerned or questions regarding wildlife.
On a personal note, I hope that I can train and volunteer for their oil spill response team. Something I am am very interested in.
Also another site is Humane Wildlife Control. They deal with 'nousance' animals and their offspring in a humane manner and as stress free as possible.
There site is very informative as well on a varity of different species.
