Both Mercedes cars ran into technical problems during the race in Montreal, but whilst Rosberg was able to nurse his car home and pick up 18 points, Hamilton had to retire with brake failure.
The German's second place means he now leads his team-mate by 22 points in the Drivers' Championship. However, Hamilton has already overhauled a 25-point deficit this season.
"Well, I've had a lot of work to do since race one - that is now two DNFs that I have had and zero for Nico. We will keep pushing and hopefully come back stronger in the next race," the 2008 World Champion told Sky Sports F1.
"I was in the lead at the time that it failed. I am two DNFs down - so that is 50 points, or almost 50 points that I have lost so I am going to have to try and recover them somewhere else."
Mercedes confirmed that "high-voltage control electronics failure lead to permanent loss of MGU-K drive on both cars in today's race" and Hamilton feels that running in the dirty air behind Rosberg caused his problems to be worse than his team-mate's.
"We knew as a team that we had some problems part of the way through our second stint, but we thought that we would be okay to manage it," he said.
"Not just me, but Nico as well, and that is why we were going at the pace we were going. I jumped him in the stop and I was thinking 'wow what an amazing feeling' then straight away that lap the brakes failed so there was nothing I could do.
"The thing is I was following him and when you are following someone you are getting more heat - he was in clean air the whole time in front and so there was not really much I could do.
"When I finally came out in front I think by then everything was already cooked so there was nothing I could do. It was an unfortunate day, but the team still got 18 points which is good, so we will move on and hope we don't have any more DNFs throughout the year."
