I placed the vid on another computer with good sound. This time I could hear a faint "whistle / screech". Still, the sound is not very conclusive. I can hear the engine running very nice.
I would do the "easy" stuff first: it could be a pebble lodged behind the brake shield - you will need to raise that wheel and visually inspect, or maybe try to back-up and apply the brakes a few times.
In straight line, a wheel bearing makes noise if it's in really bad shape. You should be able to hear a different sound (like more evident) when taking a turn towards the offending wheel. If the noise is bigger, it's definetly the wheel bearing.
I have a set of brand new front & rear bearing (in case) sourced from Rock Auto at a good price. They ship to Canada. Make sure you get good quality bearings if it turns out it's indeed them (Timken). the dealer will charge you an arm & leg. But first make sure it's not a pebble lodged in there. I had a similar sound a few winters back and it was a pesky stone from the city guys that spray the stuff on the icy roads.
