As for WVNY, I'm having trouble receiving it with outdoor VHF antennas on the south shore, so I don't think you'll be able to see anything up in Laval.
Well, since KRO is able to receive it pretty well using a home made antenna in the attic, I'm hoping I can duplicate his results.
Being in St-Eustache, he should be slightly farther (5-10Km?) and to the West from Mount Mansfield than I am.
I'm keeping my fingers crossed until I give it a try...
