There are judgments relating to environmental legislation. I'm not a lawyer, and Mr. Bélanger may be able to give you additional information. However, we know that municipalities' ability to take action to protect the environment, in particular against the destruction of wetlands to protect riparian and costal setbacks, is increasingly been recognized by the courts. The possibility of preserving natural woodlands or conservation parks in urban areas is now recognized as a right that may limit property rights.
The fact that someone owns a woodlot along a lake does not mean, for example, that they can cut down all the trees along the edge of a watercourse or lakes. The municipality can pass bylaws, and there is now provincial legislation that governs this in a case like that. Sometimes, it is in fact confirmed on the ground. There are a number of documents about this.
