In this artist's impression supplied by the ESO (European Southern Observatory) on April 25, 2007, the planetary system around the red dwarf, Gliese 581, is pictured showing what astronomers believe is the most earth like planet found outside our solar system to date. Using the ESO 3.6-m telescope in Chile, astronomers have uncovered the planet which could have water running on its surface. The planet orbits the faint star Gliese 581, which is 20.5 light-years away in the constellation Libra. (Photo by ESO via Getty Images)

Everyone wants to get something for nothing - whether it's a lucky upgrade that means you can turn left when you get on a plane instead or heading off into the economy seats, or even getting a few extra features thrown in for free when you buy a new car.

As some of the sharpest businesses around, no-one understands this quite as well as casinos and that's why they all have a system that they call comps. It's short for "complimentary offers" and these are special treats specially designed to reward you for your loyalty to the casino in question. They're basically bonuses.

For a long time the laws of Canada have explicitly banned gambling in any form. This may be the reason why the country does not have so many gambling establishments as the USA - but their quality surely makes up for the quantity. The first Canadian casino was opened in Dawson City, Yukon, in 1972 - it was the first one after gambling has been banned in the country in 1892. The Diamond Tooth Gertie's Gambling Casino did not operate for long, though. The first permanent commercial casino was opened in 1989, and it was the first of many - there are currently 75 casinos operating on Canadian soil.
