​A Brampton family is appealing for help to find a loved one who has been missing for seven weeks in Mexico, after spending tens of thousands of dollars to no avail.

Shawn Ramta disappeared while on a two-week vacation in Mexico City. His family says Ramta is a seasoned traveller who has often travelled on his own.

Raj Ramta, grandmother of the 34-year-old bodybuilder and entrepreneur, told CBC News her grandson told her he was going to the gym and would call back.

"That was the last time I heard from him," she said.

Family spends around $30,000 to find Ramta

Peel Police told CBC News their authority stops at the Canadian border and said they need Mexican police to dig up Ramta's phone records and find his last known location. They said their requests have not been answered by Mexican authorities.

Frustrated with the slow progress, the Ramta family hired their own private investigator and a lawyer. They spent money on billboard space in Mexico to post missing persons posters of Shawn. Not including the reward money, which they recently doubled to $50,000, their efforts put the family about $30,000 out of pocket. They have received no tips so far.

But for Raj Ramta, there is no cost she wouldn't pay to find her grandson.

"I just request everybody please help us get our Shawn back," she said.

"I would sell my house to get him back," she added. "I don't care about money. I just want Shawn back."
