HA/Westcoast Air
I was in Canada a couple of years ago took the train from Toronto to Vancouver (winter time heaps of snow and never seen so many trees)
While in YVR I took a trip down to Victoria Island on HA/Westcoast Air on a DHC-3T the pilot invited me to the R/H seat and he had flown float planes for around 20 years the landing was so smooth on the return trip it was a DHC-6-200 and the Co-pilot had a non Canadian accent turned out to be a Kiwi and was the CP. I saw a lot of floating logs in the harbor and washed up on the shoreline of Stanley Park so I guess they are a hazard.
