BR Powersource Ltd

Best place to get your gmc/chev diesel worked on!!!

Very honest hard working guy. Gave me advice that saved me over 3 thousand. Not many people have that commitment to customer service as Bernie.Just leave your vehicle with him and rest easy knowing it'll be sorted out.

Had a great experience... my truck was down for a day and back on the road better than ever. Big shout out to Bernie for looking after me on short notice!! #dmax

Bernie is extremely knowledgeable when it comes to tuning!!I'd highly recommend giving him a call.He tried numerous ways to deal with my speedometer recalibration but ultimately wasn't able to sort it out.He was very successful installing a tune on my Topkick pickup, that resulted in better power and significant increase to my fuel economy...Wow!!Who wouldn't appreciate an extra 100km per fill-up?Thank you Bernie!

Brought my duramax in and he is very knowledgeable on every aspect, I’ll never bring my truck to another mechanic

The best of the best. Very friendly, kind and intellegent. They live and breathe duramax and know anything and everything about them. They stick to the schedule and work quickly. Truck drives better than ever and both times I took it in, it was done the same day.

Had my truck “fixed” by another mechanic just to have it fail within a month. Very frustrating as it costed me a lot of money. After multiple references I brought it to Bernie. If you want an honest mechanic this is your guy. One of the most knowledgeable diesel mechanics in Ontario. I can’t thank you enough for your work. 10/10. If you have a duramax do not go anywhere but BR Powersource!

What can I say about Bernie and his wife Olga at BR Powersource.... well there honestly isn't words that can describe the kindest they provided me with and the knowledge of the Duramax Bernie and his wife have !I am from the East Coast, I broke down in Oakville and I am a commercial hauler. I had a 40 ft trailer loaded and they went out of there way to help me in a time of need accommodated me with a spot to park the trailer and had me in and out of that shop quicker then painter falling from scaffolding.The hospitality that you showed me will never be forgotten and if there is ever anything that I can do to help you guys out it would be an honor.If you own a Duramax this is the place to take it.If you don't you are missing a chance to be in the presence of the most knowledgeable deisel mechanic I have ever met and just amazing how caring and honest Bernie and Olga are they provided this service and only charged me for the parts NO LABOR COST... not saying this may be the case for everyone but I think they really understood the troubles I've been having with this truck.... so don't expect freebies that's not what I'm getting at..... just absolutely an unreal experience!!!Thank you very much for your service!Best Regards and keep up the excellent work people like you two are very hard to find these days !

I took my 2017 gmc 1500 to Bernie and his team last week to get it tuned and delete the active fuel management system on the truck (known to cause issues later on) and I have to say what great people they were to deal with so easy, no BS. Bernie knows what his doing. I honestly wasn’t expecting much difference performance wise. Let me tell you I fell in love with my truck all over again so much more responsive, better pick up it puts the power down way better now. Genuinely impressed. I’d highly recommend his service, you won’t be disappointed.Thanks again

My trucks have over 500k km, with Bernie’s setups and I have never needed to do anything to em engine wise, they are beasts and very reliable! Would stop in there any day in the future for another truck to be done!Very professional and nice crew
