DATABASE OF CANADIAN CLASS ACTION LAWSUITS

"The National Class Action Database is designed to give lawyers and the public easy access to court documents submitted with regard to class action lawsuits currently underway across the country" (Canada). It is a service of the Canadian Bar Association and covers 2003-present.
It does not claim to be comprehensive, however.

Is there anything like this for the USA? or other countries?
