I as well don't hold out much hope. You would not even most likely meet the admission requirements that includes (for Ontario and I am sure similar for other Provinces) two grade 12 academic maths, physics etc. Not sure, and you would not know either, if you met the CFAT requirements for the trade or what score you had. Interview for that trade not done. Seems strange that you were heavily into Arts, and now al of a sudden want to change to a tough engineering program. As indicated you cannot even put in the request until after BMOQ which will be the start of your second year. And no guarantee that you will successfully complete.
Even if you had the admission requirements, and the CFAT results acceptable and interview went well... would you have been selected this year?? Were many of the items that you received credit for as your current trade even transferable to receive similar for engineering? Not only do you have to be accepted by the prospective area but your current area has to also agree. This does not occur automatically and there individuals trying to transfer to engineering trades that are currently taking engineering courses and going for degrees.
As others have said, talk to them about it. I don't think that you are going to find the response favourable.
