not sure about rules in canada,but i happen to have some exp. with wetlands.might i add i got caught digging in wetlands for my lake.never even dreammed this was wetlands.1st wetlands are every were,it does not have to have water standing to be wetlands.you can hire a eng.and they will look at plants growing on the site and the soil and give you a good idea of weather you can dig at this site.the bottom line is if you dig and get caught it can be very bad($$$$$$$)and alot of them.in my case it helps if you are not a devolper are big contractore who knows better.you can buy your wetlands from the government for $$$$ ranging from $1,500.00-5,000.00 per acre,plus government cost.(this is the high dollar part)what i learned is don't do it,it's not worth the problems.i might add they have the write to make you put the land back like it was before you started,this is not cheap,itself.please ask 1st if you even think there is a problem.these people taught me a lesson in life.
