Visa requirements for Canadians
Canadian citizens using Canadian passports do not need a visa to enter this country for limited stays.
Visa requirements for Foreigners
As the embassy or high commission of this country accredited to Canada is physically located inside the USA, you must apply for this visa at the embassy or high commission or consulate located in the USA. These are usually in Washington DC (embassies and high commissions), or in New York City (consulates)
Canadian citizens using Canadian passports do not need a visa for short stays as tourists or on business. This does not apply to persons holding Canadian "Travel Documents" (1951 convention refugees); or to persons with foreign (non-Canadian) passports and Canadian Permanent Resident cards. This does not apply to Canadians who are using non-Canadian passports, or to Canadians going for work or study or any other non-tourist/business reason.
