4. Acid deposition is an issue in eastern Canada as many waters and soils here lack natural alkalinity like lime base and hence cannot neutralise acid naturally. Places like Ontario has it worst as their water and soil systems cannot deter the outcomes of high acid deposition.

The 9 largest coal burning states are in Midwest and Ohio River valley which is estimated to contribute to 2/3 of acid rain in Northeast and Eastern Canada.

In 2005, 50-70% of Canada’s acid rain came from the US.
