As someone from a second-tier Canadian city that had relatively few tech employers, this has definitely been a boon. Previously there was one game in town, and they attracted talent with a fancy office and above-market salaries for the region. I left after a couple years and joined a bay area startup remotely for a ~30% pay raise, and several of my former coworkers have as well. The company in question is suffering from a brain drain as old-time employees leave for greener pastures, and they struggle to attract international talent - because they didn't have much cross-polination with other tech companies in the past, there's a ton of NIH built by very smart new grads with no real world experience, and experienced engineers tend to take off once they realize the extent of the problems.
