Moana 2 is being animated in Canada

California catches fire a lot (serious problem: it's two or three times a year now, and likely to get worse), has drought problems and now flooding problems, and is basically unlivable in rentals, which isn't the studios, it's a wider problem with land values, land banking and hedge fund speculation. Owning a place at those kind of costs when you may not even be able to get fire insurance is insane unless you're banking 7 figures annually. WB is expanding its footprint in Burbank so it's not like jobs are disappearing (overall anyway) but that does take away a lot of job security because, paradoxically, all these jobs being at one studio makes it harder to stay employed if that studio's ownership decides it's time to write off three and a half billion dollars of production against tax like WB last year. Plus WB themselves are moving a lot of production out of LA and the US entirely, with projected new sites in Europe to expand existing studios there.

Canada (and most of the world for that matter) has a lot going for it, particularly in terms of land costs (which makes acquiring new land for development a lot cheaper than in LA or even in Georgia), has better healthcare (not just on cost/accessibility but on medical outcomes), is culturally very similar to the US in the ways that people like and isn't likely to undergo a weird decade of politically-motivated punishment against "the liberal media" if those in power deem such punishments as likely to play well to their electoral base, which makes it a politically stable and largely neutral place to move production to without upsetting anybody. Pols can throw their tantrums against whatever rump of production is left in LA/elsewhere, but the studios will leave over a relatively short time if that continues - just as they originally ended up in the US, and subsequently concentrated in California, after similar tantrums decimated the European studios' talent base in the 1920s and 30s and sent them overseas.
