Glad that you liked that quickie Rover ute 
I do! It immediately made me picture it in green with steel wheels as a BC Rail track inspection car, which in turn made me envision the wagon version in BC Tel colours, gold over white with a blue stripe... (as I imagine Crown corporations all used BC-made vehicles as much as possible...
Out of curiosity, what other marques were built (or assembled) in the Dominion of British Columbia?
So a summary form... after the war Hoffar was stuck with its massive plant at Lumby, so at first they got a licence from Whitcomb Locomotive to build the 65-DE-19 switcher... but the market for such is rather limited, so after Armstrong Siddeley bought HAE in 1948, they started building the Armstrong Siddeley 18 in BC from 1950. They the pickup version of the Whitley 18 was built until 1961, but the saloon was discontinued in 1959, after a licence was secured from Alvis to produce the TD21 for North American markets. TD21 variants were offered until 1964, when they were replaced by the TE21. These were marketed in BC and Canada (a small number did reach the US) under their original names - Armstrong Siddeley Whitley, Alvis TD21, Alvis TE21. In 1969, Bristol Siddeley sold the Lumby plant to British Leyland, who expanded the plant (engine factory at Dure Meadow, stamping and assembly facilities southwest of the town of Lumby - 100 acre complex with 3 miles of rail trackage inside, plus the Okanagan Glass Works at Lavington supplying glass for them, Vancouver Locomotive Works in Surrey, Supermarine, etc) and began producing the Rover P6 (in saloon, ute, and wagon versions) for the North American market there. In 1976, the P6 production was replaced by the SD1, and in 1982 a version of the Austin Ambassador was introduced as the <Rover? Leyland? Hoffar? Dogwood>. Hoffar Auto (and after 1969, BC Leyland) made wheel assemblies for DHBC starting with the DHBC-5 Swan and continuing through the DHBC-7 Trident and DHBC-9 Kehloke, and also for Supermarine for the Shukopoots and the Spitfire II. They also made the various Land Rover types for the BCDF and civilian markets. BC Rover-Leyland has been an independent company since... dunno when.
There's a bunch more to figure out with the details of that, this is just what I have based on little tidbits dropped here and there (e.g. the wiki page for BC Rail's Lumby Line)... like, need to work out the more complete ranges, domestic developments, etc.
Others - Ford BC had a plant in Burnaby that made TT and AA trucks before the war... during the war made aero engines; I don't know what they were doing post-war, but the plant was closed/repurposed by the mid 80s. But currently the only other vehicle manufacturers in BC are Bedford of BC (GM subsidiary, plant located in the Pontypridd suburb of Blaenau [west side of the river, north of the railway]; they build a lot for the BCDF), and Hayes - both build HGWs, Bedford also does busses.
BC-built cars were cheaper after 1960 due to tariffs introduced on imported cars, so foreign cars were a luxury... in 1962 British, Canadian, and Australian manufacturers were made exempt. By the end of the 1960s the Americans had stopped complaining about this, with GM and Ford deciding instead to send Holden and Australian Ford products into BC [the Guichon Auto Terminal in Port Guichon, Ladner was opened in 1970 to handle cars coming from Australia], while Chrysler began manufacturing right-hand drive versions of some cars in Canada (much sought after nowadays by collectors are RHD versions of the Dodge Charger and Challenger). And then since the 80s since a deal between BC and Japan was made, Japanese cars have grown in popularity too (a pleasant byproduct for fans of Japanese cars in Canada and the US is that BC by and large gets J-spec production, so not uncommon that Silvias and Skylines sold in BC were actually to US and Canadian buyers...)
... ... ... all this has made me think, I have a particular fondness for AMC (you all already know I'm weird), so maybe I'll brain out something to link Rover-Leyland and AMC... maybe no Renault connection for AMC, but Rover instead, and the resulting union is fruitful, and now... ooooh. I can feel some fun times coming up with this thought.
