Wildlife killing contests take place in many countries. The Humane Society of the United States has published facts about the contests in the USA.

The practice is brutal. There is little regulation around the killing. They kill animals of all ages. Pregnant females have been killed. Mothers have been killed, leaving their babies to die. When they kill so many predators at once in an area, it destabilizes the ecosystem.
From an ecological point of view these contests are a terrible mistake. From a human point of view they are a mistake. The contests encourage behavior that makes us less human. Going out to take life for prizes is not exactly something we should be aiming for. How about a contest where we see who can do the most acts of kindness. That would benefit every one. A pile of dead coyotes benefits no one.

As far as I know, these horrible "competitions" are only held in the USA and Canada. I have not heard of any in Europe, Asia or Australasia - but I cannot say for sure.

There is a little progress, apparently, as some states have started banning the competitions on a local level. See:

It looks like you are right about killing contests being a North American thing.
Canada has them, but not as many as the USA because we have a much smaller population
Any bans in Canada will have to come on the provincial level. So far I don't think any have been banned.

The USA is similar in that their bans will have to come at the state level.
Some states have already banned killing contests. I think it will take a long time for the country to be free of killing contests. 
Some states will not give up contests until they have to. 

They are going to have to change how people think about animals, especially predators like wolves and coyotes.
