Verstappen has frequently been criticised this year for making a series of errors which have cost Red Bull a huge chunk of points.
But the Dutchman tried to put those early-season woes behind him and he drove an exemplary race in Montreal.
The 21-year-old was the quickest throughout practice and secured a third-placed finish for his team.
And Rosberg believes Verstappen had the attitude usually accustomed to four-time world champion Hamilton over the weekend.
“Verstappen – epic weekend,” Rosberg said on his official YouTube channel.
“He showed a bit of Lewis Hamilton attitude to me this weekend.
“When Lewis is angry, he is at his best. He channels it into an unbelievable performance and I think Verstappen had some of that this weekend, so he gained this extra focus from the word go.
“He was first all the way through [practice], great qualifying, and finished third. I think that was a really good weekend from him.”
Meanwhile, Hamilton finished a disappointing weekend fifth – a result which saw him drop behind Sebastian Vettel in the Drivers’ Championship.
“Lewis had one of those off-weekends totally,” he added.
“Ok he had an engine thing in the race, but even so qualifying was still off.
“Typical for Lewis – these phases, he loses a bit of motivation when things don’t go well.”
