If you want to do something artistic or start a business based around Art, Montreal is perfect for it, for the very same reason above.
Initially the govt invested in the arts to preserve French culture, which resulted in a lot of art infrastructure being made, cheap ateliers, fabric suppliers, paint suppliers, &c. Which attracted a lot of artists, which then increases the demand for the art infrastructure, which makes the city easy to make art in.
It makes it stupid easy to make stuff and find the skilled artisans you need to make it. Much easier than any other Canadian city I've lived in.
West coast filmmakng started in the Bay Area (at the time the largest conurbation in the west) but moved south because of the year 'round weather.
But why the west? Because Edison controlled the filmmaking patents and demanded not just royalties but script oversight as well. By moving west, they could ignore the patents because they were simply too hard to enforce from such a long distance.
So ironically, given how things worked out, IP piracy is at the root of Hollywood.
The only reason I even commented was because IP issues are popular and relevant on HN
Same thing with Israel -- if they had some easier way to make moneys they would go for it. But constant demand from their defense kept if afloat.
