Don't know if this is the right forum but are there any casinos that offer candians etc decent exchange rates for entering their events.

Call a bunch and ask. The rate will be independent of whether you enter a tournament or not, so exchange where you find the best rates and then play where you want. When I had some Australian currency to exchange years ago I found wildly different rates from one casino to another. Like 8% different. I think the best at the time was the Hard Rock, but that may have changed. They offered a rate slightly better than my bank.

Also call private money exchange services - there's one near the strip called "Foreign Money Exchange"

Edit- with WSOP coming up I assumed you were asking about Las Vegas, but the same is true wherever you go. Call the main number of the casino and ask for the main cashier. Also go to google maps and search for currency exchange.

thanks for the feedback. Yes am planning vegas for the senior events
