Need to build a new dock. Old one is just about done.
It'll be a floater like the old one.
The question is wheather pressure treated wood or
cedar is better. The problem with pressure treated is the arsnic
content. For a dock that swimmers and skiers will be sitting on and
pulling themselves up on, that's not so good. Cannot always get
pressure treated without arsnic.
How well does cedar hold up to extreme weather condiitions.
Fresh water, Canadian winters and all that.

The hard science of whether a PT dock will kill someone is secondary to
perceptions. Sooner or later you'll have a guest that won't let their
kids play on it if it's PT, and sooner or later the local newspaper
will report that mysterious substance X is in the lake and maybe it's
coming from someone's PT dock. Nothing will beat being able to say that
your deck is just good old 100% cedar as you put your feet up in your
Muskoka chair and open another Blue Lite.
