There are dozens of fake e-visa and ETA travel authorization websites plaguing Google search results right now trying to collect your personal data and passport information (and credit card info in some cases). Some of them will indeed provide you the ETA authorization, but they simply apply for that on the government website and then resell it to you for 10x markup. Others are simply phishing websites, and they never provide you anything it is just a scam to collect black market PII on travelers (personal data brokers). Please ensure you are using the government website only when you request ETA!
