It takes time and Canadian standards are high. You are expected to have a first-rate resume, to be fluent in English or French (depending on the area) and to have relevant work experience. You will also need a work visa. And getting a job offer in Canada is, by design, very difficult.
In general, to hire a foreigner, a Canadian employer needs to obtain what is called a labor market impact assessment, which is an official decision on whether hiring that specific alien would benefit Canada or not. If the evaluation is negative, the job offer is void. There are certain types of work that don't require an LMIA, because they are exempt under NAFTA. However, Donald Trump hates NAFTA, so those windows of opportunity could close at any time.
In the popular imagination, there is a persistent idea that the border between the United States and Canada is not real. When I arrived in Canada, I found work in 15 days, but I know that's not what happens in most cases. It can be difficult to find work in Canada, but if you have patience and keep a positive attitude, you'll eventually get a job. To make sure your career is in demand, go to job search websites and see if there are any jobs in the city you're thinking of moving to.
Remember that Canadian employers want to see people working for them who work hard and who are willing to do the extra work and willing to learn and adapt to whatever job they're doing, even if it's one that's a little less qualified. Many people have complained that it's difficult to get a job in Canada for immigrants and foreigners because Canadians expect you to have Canadian work experience before they hire you for the job. However, I have a lot of friends who work in other industries and it took them a long time to find work in Canada. Employers will see this as a step in the right direction when it comes to finding a job in Canada.
All candidates receive a score of up to 1200 points, according to a complicated rubric designed to eliminate anyone who may have difficulty assimilating. Nobody wants to re-learn things they think they already know, but in Canada it's good to take a step back. In fact, it's probably harder for immigrants to find work in Canada than anywhere else and it's not due to a lack of jobs or a bad economy. The maximum possible score without a Canadian job offer or without Canadian work experience is 470.
If you are a U.S. citizen, you can apply for a Canadian work permit or apply for a job in Canada under the Federal Skilled Worker Program, which could eventually lead to the Canadian PR. You have to be willing to give, which means that you may have to accept a different job that you didn't want. Points are awarded based on the person's age (people aged 20 to 29 get the highest scores), education level (the more advanced a person's university degree, the better), language proficiency (it helps to know French) and work experience (only qualified occupations count and there are additional points for people who have worked in Canada).
Thanks to the USMCA (United States-Mexico-Canada Agreement), it's much easier for a citizen of the United States to obtain a work permit in Canada.
