As a Canadian citizen, how long can I stay in Thailand on a tourist visa including extensions?

A Canadian citizen applying for a tourist visa can stay in Thailand for 3 months for a single entry according to the latest information. It's essential to clarify whether this period includes the possibility of extending the stay. A commenter suggests that Canadians can travel visa-free for up to 6 months by utilizing a visa exemption policy and extending their stay, indicating that you can extend your stay by 30 days after arrival and then exit to a neighboring country like Cambodia before returning.
