Here's why:
* International travel requires a passport: The US government requires all citizens to have a passport for international travel. This rule applies even for short trips like yours.
* Passport photos are mandatory: Passport photos are a mandatory part of the passport application process. Even if you personally avoid photographs, a passport photo will be required for your document.
Important notes:
* Border crossing requirements: While the Canadian government accepts US passports for entry, make sure to check for any specific requirements for short-term visits, such as visas or temporary entry permits.
* Alternative identification: While a passport is generally the most accepted form of identification for international travel, you may be able to use alternative forms of identification, like a government-issued ID card, for travel by land or sea. However, it is always best to confirm these requirements with the relevant border authorities.
It's always advisable to contact the relevant authorities at the US and Canadian borders for the most up-to-date information on travel requirements. They can provide you with the specific guidelines that apply to your situation.
