I have seen snowy owls on the tundra near Churchill, Manitoba, Canada while on a polar bear "tour".
I was fortunate to see a Great Grey Owl near a parking lot at Simon Fraser University, Burnaby, BC, Canada, unusual to be on the coast more likely to be seen in the interior of the province.
Most recently, a Barred Owl in Francis Pennisula Park, Pender Harbour, BC, Canada - chasing a Stellar's Jay, with another Stellar's Jay trying to prevent the attack.
