I'm a foreign worker worker who graduated from a top school in Canada but now work in Silicon Valley. Interviewing in Canada was a nightmare, I was called back 3 times to interview more and more people for the same company, salaries were abysmally low and I felt a general cautious vibe / old school bureaucracy in hiring.

There are hundreds of thousands of wannabe tech immigrants stuck in the broken US immigration process who should be prime targets for Canadian Tech Companies. But the fact that these people would rather be abused by lifelong delays imposed by US govt. than instantly get a Canadian Residency and Citizenship is testament on how unattractive opportunities in Canada are.
