LSTSB,
Well, I have received more help here at TV Fool than I have given and I owe a lot to Rabbit 73, Groundurmast and others. I hope one of those talented and knowledgeable guys chimes into help you.
I know enough to be dangerous . The one thing that stands out to me is the tree issue. It may be that you cannot go high enough with a practical mast or tower.
Personally, I also have a black maple directly inline with my main mast, but built an unorthodox 10' tripod (think mini tower) with 35' of mast above it on top of my roof. 8 guy wires help support it. I was able to "shoot the gap" between the top of the maple and a an adjacent oak tree, it barely makes it.
From 400 feet away up my street (gradual upgrade) hill. It looks hopeless...
I have always tried to get a pic from behind the antenna but taking a pic at ground level doesn't show what the antenna "sees".
If you are behind a large maple what you get set up now may not work in spring. Being in Canada, I assume your maple has shed it's leaves by now. You may need a temporary set up for testing and have to revamp in the spring. My neighbor who is blocked by the trees in my yard uses a bay type antenna at about 15' AGL. His only hope was to get some wayward signals above/around my trees. He uses a CM 4228 HD. He has just enough signal strength to get most channels...And of course the CM 4228 really isn't a VHF antenna either, so for VHF you would need a MCM 30-2476 or 30-2475. Best antenna value out there in a day and age when most antenna companies have dropped their VHF only antennas:

I think from behind your trees you will absolutely need a "bay type" antenna as they are best at diffraction reception:

Good info here too:

Extreme measure, read at the bottom about overlapping fields etc... very interesting:
Can you post a photo of your property showing your roof and trees?
