Speaking of a owner,most of people are still comfusing about this.
S/he could be able to a owner of a business/company but not a owner of SOMEBODY.
When you visit a company and ask someone like,
"I have an appointment to meet the Owner(of your/the company)
at 3pm ..."
And they might response,
"The Owner is just getting another call right now...”
They won`t say like "My owner is ...." which is wrong.
Even English-Canadians could make a mistake as well.
