Did you have a guide alongside you while you hunted or were you self-guiding out of an outfitter's camp?
How far north in Ontario were you? Near Thunderbay or further south or north?
What dates were you in camp? (I didn't read your original post so I'm assuming you were bowhunting)
Were you (or someone with you) calling? What calling techniques were they trying?
Sometimes even when you do everything right and all the stars are in alignment, seems no one may have told bullwinkle about it!!
