I just learned that recently - I was at a quick oil change place and asked them to quickly look at my brakes while down there. After some commotion their manager came over and explained (In a friendly fashion) they are technically a "lube shop" with "lube technicians" and not licensed mechanics and cannot do or say anything but change my oil and maybe fill up the fluids / change wipers. Interesting!

> Automotive service technician (transmission) trade certification is compulsory in Ontario.
> Automotive service technician (steering, suspension and brakes) trade certification is compulsory in New Brunswick and Ontario.
I feel you've typed that out of best thoughts and Intentions but no actual knowledge, which is an alluring and common but slippery path for all of us :-)
In Ontario, as parent and I indicated, it's a compulsory trade. It is, in fact, a government regulation directly.
