In Canada, 8 oz is a common size for small hot beverages, primarily used for everyday drinks like black coffee and hot tea. This capacity satisfies single-serving needs without compromising insulation efficiency due to an oversized cup, making it frequently used during breakfast hours and in office settings.

The 12oz size is one of the most widely used standard sizes in the Canadian market. Compared to the 8oz size, it offers a more generous serving volume, making it ideal for hot beverages meant to be enjoyed over a longer period. Its cup height strikes a balance with a comfortable grip, and it has been adopted as the primary size by numerous chain coffee shops for long-term use.

The 16oz size is primarily used in Canada for large beverages, including lattes, hot chocolate, and cold drinks. This capacity is better suited for sipping slowly and carrying on the go, serving hot drinks during colder seasons and cold beverages in summer. Its applications are stable and clearly defined.
