Thank you Dianne for all your talent, experience and humanitarian aspects of environmental law. I too have a passion for the environment. I have come out retirement to pursue natural magnetic solutions used by the American and British governments to reduce pollution and energy costs. ____What do you think about the new cap and trade law in Ontario Bill 185?______Thanks again Roman Kulesza CET President Clear Sky technology
Thank you, Roman. Very much appreciated.

I am optimistic about the new cap and trade law in Ontario, but it won't mean anything until we have regulations to actually establish a greenhouse gas trading system. I'm also one of those who believe that a carbon tax is preferable to a is preferable to a cap and trade law, but either is better than nothing.
best wishes

Dear Dianne,
There exists a Municipal law over noise control in Montreal. Or every borough rules out according to their by-law.
Thanks,
