NASCAR will not return to the Circuit Gilles Villeneueve in Montreal next season, ending a six-year run for the Nationwide Series.
Promoter Francois Dumontier announced Friday the end of the agreement, which had been operated on a year-to-year basis.
NASCAR said it wanted to return to Montreal, but could not work out a sanctioning agreement with Dumontier's promotion group.
NASCAR hopes to still be racing in Canada next season, possibly with the Truck Series. One potential venue for NASCAR is Mosport International Raceway in Toronto.
NASCAR also plans to fill the void left by Montreal in its 33-race schedule, which has yet to be announced. NASCAR's preference is to explore new markets where it's not currently sanctioning national series events.
