When it comes to tipping in Canada, we follow very similar customs as you would find in the USA. Aside from situations wherein a gratuity is automatically charged by an establishment, always remember that tipping is your choice. Sometimes the service is worth a tip, but other times it is not. Below is a list of what is considered normal for tipping procedures in Canada.
Please note that all amounts shown below are in Canadian Dollars(CAD). If you wish to tip or pay for things in US Dollars(USD) it is generally accepted, however, it will be treated as $1 USD = $1 CAD when in reality the exchange rate is approximately $1 USD ≅ $1.25 to $1.30 CAD. This means that you will be overpaying by a significant margin.
If you wish to exchange money for Canadian Dollars, it is recommended that you do so at your bank before leaving home, or at a bank in Canada as airports will offer you a poor exchange rate.
