United States Citizens:
If you are traveling from the United States, you need a Passport to enter into Canada. If your passport expires at any time in 2016 you need to get it renewed before traveling to Canada.
Outside the United States:
If you are from outside of the United States, check to see if you need a Visa: http://www.cic.gc.ca/english/visit/visas.asp
If you need a Visa, you likely need a letter of invitation. If you need a letter of invitation to attend General Conference, please find out if your letter needs to be notarized and send a request to conferences@MCCchurch.net.
Here is more information on the letter of invitation: http://www.cic.gc.ca/english/visit/letter.asp
If you are traveling to Canada and have a lay-over in the United States and are not a US citizen, you may need a travel visa for the layover. Please check here if you need a visa.
