Nice find! It's very early in the year for Laetiporus sulphurea, Chicken of the Woods. I note differences between the fruiting bodies in your region from where I live. Here, they are much more orange on the top, more spaced apart vertically, and less fleshy in structure. I don't know of anything remotely similar to L. sulphurea, so unless there are species in your area that are similar to it I reckon you have good reason to enjoy your delicious harvest.
Thanks!
You're welcome! You'll note that they are nice and orange in the first picture, but much more yellow in the others. Those photos were taken a few days later, when the mushroom was past its prime. The lighting is also very different because of all the pollution wafting south from Canada. It's really eerie, makes the sun look like this:
