Do Canada passport holders need a visa to visit KH?

Canadian passport holders need a visa for Cambodia. The easiest option is the official Cambodia eVisa (Tourist T-class), applied online before travel for a 30-day single-entry stay. Visa on arrival is also available at major airports and land borders. Canada and Cambodia have no visa-waiver agreement, so Canadian ordinary passport holders must obtain a visa for a tourist visit. The recommended route is the official Cambodia eVisa (Tourist visa, Type-T) issued by the Ministry of Foreign Affairs and International Cooperation at evisa.gov.kh. It is a single-entry visa allowing a stay of up to 30 days, valid for 90 days from the date of issue, with processing of about 3 business days. The government fee is USD 30 plus a USD 6 processing fee (USD 36 total). A visa on arrival (USD 30) is also available at Phnom Penh and Siem Reap-Angkor international airports and major land crossings. Separately from the visa, all arriving travelers must complete the free Cambodia e-Arrival form (immigration, customs and health declaration) online within 7 days before arrival at arrival.gov.kh. Passports must be valid for at least 6 months and have at least 2 blank pages. Cambodia is in Southeast Asia and is not part of the Schengen area, so the Schengen 90/180 rule and ETIAS do not apply.
