I was in the same boat almost a couple years ago -- and also being in Vancouver I can understand the environment. I thought I was the only gunner in my group of friends so I stayed quiet until suddenly one of the other people in my group announced that they had just passed their CFSC and I was like: wow, guess what?
The thing is, your hobby will eventually come out among your friends. Friends talk about what they love and what they are doing. What would be stranger is if you were friends for years and then suddenly they discover you had this 'hidden hobby'. The way I see it: gun owning is LEGAL and a FUN hobby and there is NOTHING wrong with it. And I will tell anyone that.
In fact I would be overjoyed if my friends shared with me my hobby and I have taken over a dozen of my friends (and even one I didn't know that well) shooting at the range. All except for one came away with at least a more positive impression of the pursuit and with way more education on the subject than from what they've been reading in the media. And even two of them have said they would get their PALs.
And surprise, even those who have declined my offer or who I know are definitely anti haven't felt the need to break relations with me, despite what people in this thread suppose. I still go out to concerts, have lunch with, go to parties with, play with their babies, with all those friends. Guns do not consume my life, they just consume a lot of my disposable income! Those people who have suggested you get new friends are goofs. They don't live your life any more than you live theirs.
Keep on being the well-rounded person you are and humanize gun owners to your immediate circle. They will see the hobby as a normal pursuit that people THEY know and love can safely pursue.
