Certainly with regard to the ecological gifts program, it should go without saying that if you extend the capital gains exemption to all gifts of real property, you've pretty much cut the legs out from under that program.
It serves as an important incentive. It has a tax policy based on the government's overall protection of the environment policy. It is somewhat related to the policy with respect to charitable giving, but it has a very independent policy basis.
If you extend the capital gains exemption to all gifts of real property, you put donors in a situation where they get the same tax benefit if they give sensitive land to a hospital, a university, their church, as they have if they gave it to an environmental charity.
There is no protection that goes along with the tax benefit. The Canadian Land Trust Alliance certainly takes that view with respect to that measure.
