Marcus Ericsson won the inaugural Ontario Honda Dealers IndyCar race in Markham on Sunday [1].

The victory marks a successful debut for the new street circuit located in the suburbs of Toronto, expanding the series' footprint in Canada.

Ericsson, driving for Andretti Global, secured the win by overtaking Romain Grosjean during the final stages of a chaotic event [1], [2]. While reports on the exact timing vary, he passed Grosjean between four and five laps before the finish [1], [3].

This result represents the fifth IndyCar win of Ericsson's career [1]. The race took place on Aug. 16 at the newly established Markham circuit, which hosted the first edition of the Ontario Honda Dealers Indy [1], [4].

The event was characterized by high volatility, requiring drivers to navigate the unfamiliar street layout. Ericsson managed to maintain his lead through the closing laps to claim the top spot on the podium [2].
