Tickets aren’t officially on sale yet for the Toronto production of “Hamilton”, but online re-selling sites are already falsely promoting that they have tickets to the show.

According to Mirvish spokesperson John Karastamatis, tickets go on sale Oct. 28, and the only place you should purchase them is through Mirvish.com.

If you buy tickets from re-sellers, you might still be able to get into the show but it is likely that you have overpaid, Karastamatis said.

However, people have been turned away at productions after purchasing invalid tickets from re-sellers, he warned.

One of the giveaways for online re-sellers, is if the currency for the “Hamilton” tickets is anything other than Canadian dollars.

“At the Ed Mirvish Theatre in Toronto they offer tickets in the last row of the orchestra for $1,145 (U.S) each, plus service fees of upwards of $120 (U.S) per ticket,” according to a media release from Mirvish Productions. “Yet the face value of tickets will only be $50 to $250 (Canadian). This is a mark-up of over 700% of the face value.”

Karastamatis warns that there is not much the production company can do if you buy a counterfeit ticket. If you paid using your credit card and find out before the show that your ticket is not valid, Karastamatis suggests calling your credit card provider and explaining you did not receive the product you paid for.
