Hi fabbers!

I'll be traveling to Vancouver next month for a conference. I know it tends to be a bit more temperate than other parts of Canada, but can anyone give me any more detailed info about the weather? Do I need to pack scarves, heavier coats, or will I be okay in just a mid-level jacket? I have only been there once and it was in the middle of the summer.

Also, do you have any can't miss suggestions for sightseeing and or local shopping? I'll be staying near Gastown but won't have a car. I did go whale-watching when I was there a few years ago.

Thanks in advance for your collective wisdom!
