After having created a map for Counter-Strike: Global Offensive modeled after a Montreal subway station, two Canadians could face a fine of CAN$50,000 (about $49,200) if their design is made public.

According to the Journal de Montréal (Google Translate), Diego Liatis and Frédérik Denis spent nine months making a detailed digital version of the Berri-UQAM station. The pair hasn't released the map to other Global Offensive players yet, but they did release a YouTube trailer last month, followed by a second trailer on February 17.

"I would like [the Montreal transit authority] to show me the law that forbids me to reproduce a public place," Liatis told the paper.

The pair have been working on their map in preparation for a LAN gaming competition held at a local technical university, the École de technologie supérieure de Montréal in early March.

Liatis and Denis did not immediately respond to Ars’ request for comment.

Liatias has told Canadian media that he had asked the local transit authority, the Société de transport de Montréal (STM), for its permission—and he was denied. According to Liatis, the STM cited potential “panic” among its riders as the reason for the lack of official permission.

STM spokesperson Amélie Régis told Ars that it would not comment on the cease-and-desist letter it sent to Liatis, “because they are private legal matters.”

“We usually take appropriate measures when someone uses our brand without permission,” she added.
