A Canadian woman has filed a complaint to the national post after a postcard sent by an Argentinian friend had the spelling corrected and with the words "Learn English!!" in red pen.
Mirella Zisko from Toronto received a postcard from a friend on January 12, and was shocked to find that it had been corrected with red pen, she told CBC News.
The man, named as Oscar, who speaks English as a second language, emigrated to Canada but returned home to Argentina for a visit.
"First I was mad, and then I just felt upset for him," Ms Zisko said. "He's such a good friend, and he's an older gentleman, and I just felt hurt for him that someone would go out of their way to be mean.
"It's 2017. Who has the right to do this?" Ms Zisko told CBC news.
Ms Zisko said that she doesn't know who corrected the postcard but said she doubts it was done in Argentina where the main language is Spanish.
Her daughter, a university student, called the writing "racist". "She's like, 'This is wrong, this is racist. It's 2017. Who has the right to do this?'"
She complained to Canada Post, and asked if tampering with someones mail was a crime.
The postal service, told the CBC that the incident was unfortunate and that they understand why Ms Zisko was upset.
It did not clarify whether this incident could be considered a crime adding that "with many hands touching the postcard before and after it entered Canada, it is impossible to determine where and when the marking may have occurred."
