This assessment report is a compilation of scientific research and monitoring on acid deposition and its effects in Canada. The assessment, conducted by experts from federal and provincial governments and academia, presents the current state of knowledge of acid deposition. Despite widespread misconceptions that the acid rain issue is solved, new research indicates that the problem is persistent. Between 21 and 75 percent of eastern Canada, continues to receive levels of acid deposition in excess of critical loads (i.e. the amount of acid deposition that a particular region can receive without being adversely affected).
