Parents Applied for SIN Card on the Wrong Website

My parents were applying for a SIN card online and my father mistakenly went to a third party website that looked legitimate to him, here is the website- https://sinservices-ca.org, where he entered literally ALL HIS INFO, including personal documents like passports, names, PR Card and old SIN number. When he reached the last page, it said to pay $95. He didn’t think much of that because lots of service do ask for payment. Then he did the same with my mother’s application and paid another $95. After he was done with this, he asked me whether he would’ve had to pay had they gone in-person to Service Canada. While I was looking that up online, I found out that applying for a SIN is completely free! He showed me the website and I told him that this didn’t look like a government website. I was thinking it could be a third-party website or a scam. Either way, we called his bank, BMO, and let them know that he was misled to pay a total of $190 for applying for a SIN card.

The BMO representative said that the charge had been approved and, although they blocked his current credit card and are sending a new one, the dispute might take a few days.

I wanted to know whether anyone had a similar experience; whether the website is indeed a third-party website, which asked for payment, in which case he won’t get his money back; and also whether banks like BMO cooperate and dispute the charges successfully.

Any advice is appreciated.
