From talking to the Canadian side of the family, the bears are to be given a wide berth just in case. When they wake up after hibernation they can be cranky - which is only to be expected after that long without food. Also the old adage is that if you can't see the mountain lion, it's time to think it's because it's stalking you. There's also been a few reported coyote attacks in Stanley park this summer. It's quite an eye opening reminder that nature is red in tooth and claw, and without a gun or bear spray us humans are soft and chewy to a lot of animals.
In other news, there was a programme maybe about 5 years ago where unemployed youths were taken from the UK to places around the world to try the world of work. I think one episode was a window cleaner doing high rise rope work in Vancouver. One of the three ended up staying and dping some graft.
