Because Canada is so vast a country with so many varied tastes, it is difficult to give specific examples of what people do when they go out without using generalizations.
People will go to pubs to drink and eat with their friends and families and they will go to dance clubs to dance the night away, listening to every musical style from reggae to rock to jazz to country to dance music. Many colleges and universities have their own campus pubs where people gather to socialize. Going out to coffee shops to socialize is common.
Indoor sports such as bowling and pool (billiards) and even indoor mini-putt are popular.
