Do Canada passport holders need a visa to visit LS?

No visa required. Canadian ordinary passport holders can enter Lesotho visa-free for tourism. An entry stamp is issued at the border; the visa-free stay is up to 90 days under Lesotho's visa policy, though the Government of Canada advisory notes a typical 30-day permission granted on arrival that can be extended in-country. Lesotho is a small, mountainous kingdom completely surrounded by South Africa and is NOT part of the Schengen area, so the Schengen 90/180 rule and ETIAS do not apply. Canada appears on Lesotho's list of visa-exempt countries, granting Canadian citizens visa-free entry for short tourist visits. Lesotho's official visa policy lists Canada among the countries permitted up to 90 days without a visa, while the Government of Canada's travel advisory states tourists are generally admitted for up to 30 days on arrival (extendable in-country). Travellers simply need a passport valid for at least 6 months beyond the intended departure date and receive a free entry stamp at the port of entry (Maseru Moshoeshoe I International Airport or land borders such as Maseru Bridge from South Africa). Note that Lesotho's eVisa system is currently SUSPENDED according to the Ministry of Home Affairs, but this does not affect Canadians, who do not need a visa for short tourism in the first place. Since most arrivals are by land from South Africa, travellers should also confirm their South African entry status. To be conservative on duration, plan around the 30-day on-arrival figure cited by the Government of Canada and request an extension before it expires if a longer stay is needed.
