Fun facts

In Canada, tipping, leaving a gratuity, is common practice and the proper etiquette when paying for a meal at a sit-down restaurant. Generally, tipping 15% to 20% of your final bill is considered to be the norm, especially if the service was satisfactory.
Although many restaurants around the world include the service charge in the price of the meal, this is rarely the case in Canada. Most restaurants will leave tipping up to the discretion of the customer.
