The concerning conditions of the Montreal Masters 1000

Last year, the ATP Toronto stood out as one of the fastest tournaments on the hard court circuit. However, the data from this year at the ATP Montreal 2026 has come to light, and the findings are completely opposite, even concerning, prompting complaints from several players on the tour. 

35.4 CPI for Montreal, it was 44.7 in Toronto last year, completely opposite conditions.

To put things in perspective, last year ATP Toronto had a CPI of 44.7, which led to an expert fast court player like Ben Shelton winning the tournament. However, this year in the ATP Montreal the CPI is 35.4, a figure far too low for a tournament of this kind. This causes less frequent players in reaching the final rounds of these tournaments to go further, and the top specialists have complained about it.

Fils complains about the conditions of ATP Montreal

In fact, the statements by Arthur Fils, who is not adversely affected by these conditions as he also performs well on slow courts, have surprised many. Still, he said that ATP Montreal felt like playing on clay again, which gives an idea of how this tournament is being experienced.

In Indian Wells and Miami, the CPI was above 39, meaning the Canadian Masters 1000 is up to 4 points lower than other fast court tournaments thus far. All this considering Indian Wells is itself considered one of the slowest tournaments on this surface. For example, a tournament like Madrid on clay had a CPI of 29.8 this year, indicating that the difference with Montreal is nearly similar to the difference Montreal has with Indian Wells or Miami.
