Vlad, rather cool radio and for $18, I would have driven much more than 16t minutes or miles.! It does appear to be a TRF radio, my guess being 2 RF amps, a "plate" or "biased" detector and what looks like 2 '45s or 47s in push-pull. The '80 rectifier is likely a modern (1948 or later) replacement. I have 2 RCA 80s like this; they look like a 5Y3 that they put a 4 pin base on. The 80 and 5Y3 have identical specs, but the newer ones are much more rugged. The radio reminds me of the US Radio and Television "Gloritone" 26, except tht your set has 2 output tubes.

I have 2 Canadian radios, a Bulova battery radio (Rogers tubes, they would have been RCA if a US model) and a Canadian Victor Talking Machine (RCA) R-28 radio. 2 unique features of this radio are the Ontario Hydropower approval sticker (kind of like our Underwriter's Laboratories) and the red sticker of the warning that they must purchase a license to use the radio.
