I caddied on the Canadian Tour for a number of years, mostly BC Open at Point Grey but then moved to the Island and did Qualifying school at Morningstar for a number of years and the Payless in Victoria.
At Q school I would hook up with a golfer coming up who knew one of the guys I had caddied for, mostly Californians.
For caddies that just meet up with a player at one tournament, most of the Can Tour guys, except for the cheap ones who make their wives or girlfriends loop for them, you get a daily rate - was $40-$75 a day depending on the golfer, and a bonus at the end of the weekend if they make money.
On the big tours caddies get weekly rate and percentage of the winnings, 10% of win, 6-8% top 10 and so on - it's been a while since I've been out there so it may have changed.
Many permanent caddies also get a salary for booking travel arrangements hotels etc.
Met some great people including a young Mike Weir who was very nice to everyone and always said hello.
Lots of fun and if you are into golf I highly recommend giving it a try next year when the Can Tour hits town, they are always looking for caddies.
