discrimination against autistic people

i was refused service on my vehicle by the mechanic due to "the condition of the interior of the vehicle". i took the service manager and the mechanic to the vehicle and asked them to complain, the mechanic complained that he was allergic to dogs and my van smelled like a wet dog. i have asperger's syndrome, a form of autism, and my dog acts as a sort of service animal, so she accompanies me almost everywhere. i left her at home today knowing i would have to go into a mechanics to deal with my vehicle. i explained all this to them, including the fat that im in toronto o n a family emergency, but i was still refused service because the van smelled like a dog. i asked to have another mechanic do the work that dd not have this bullshit allergy and was refused, i offered to drive the vehicle into the bay MYSELF and was still refused service. this is discrimination and i truly believe that their attitude cha ged considerable when i mentioned that i am autistic, and this will be forwarded to the human rights commission. customer care was useless, going so far as to blame me and my condition for the problem with the mechanic and that they have the right to refuse service to ANYONE for ANY REASON. not in this day and age. ill be starting a campaign against canadian tire and their attitude towards the disadvantaged. i was not even offered an apology and now im still stuck with a vehicle that does not work and the feeling that im a second class citizen because of my condition.
