The 18-year-old is the son of Canadian billionaire Lawrence and his employment has been plagued by accusations that he has only been handed his opportunity due to him being a paid driver.
His critics were given extra fuel during his recent shaky performances in testing in Barcelona but with just over a week to go until the season starts in Australia, Stroll has insisted he is ready for the challenge that awaits.
"I don't care about the critics. It's none of my business," Stroll said. "We're all professionals. Things happen in motor sports and you've just got to bounce back from it.
"It's all pretty straightforward to everyone. It was a frustrating [first] week but we set our minds on [test two] and did a good job.
"I think it's quite OK but it's not the time to be focused on lap times. We've still got to stay calm and I don't think we really need to set an objective."
