For a lot of Canadians the best IT jobs are working remote for US firms since they pay so much better than our own. Maybe that’s a potential avenue to explore. Alternatively have you thought about getting married or perhaps your common law already and get those spousal benefits?

Definitely make sure your LinkedIn is up to date and apply to as many roles as you can everyday. Feel free to DM me your profile and what kind of jobs you're after and I'll gladly give you my take if you'd like. Stay positive and optimistic, the right role will come.

I'm not familiar enough with this program to help beyond letting you know that it exists, but... US citizens who work in specific professions can take advantage of CUSMA: https://www.canada.ca/en/immigration-refugees-citizenship/corporate/publications-manuals/operational-bulletins-manuals/temporary-residents/foreign-workers/international-free-trade-agreements/cusma.html

CUSMA work permits allow you to become a temporary resident. Once in Canada, you can apply for common-law or spousal sponsorship after living together for a year.

Or if you want to apply for permanent residence off the bat, look into the Federal Skilled Workers program (FSW) that's administered through Express Entry. If you have questions about FSW, let me know and I'm happy to provide some other resources you can look into.

I don’t work in IT, but I have had luck doing this. Go on the local stock exchange (tsx for Canada) pull a index fund which manages companies you are interested in applying for (tttk for IT in the tsx). Review the company list and start applying. This gives you a list currently high performing companies that have enough presence in the country to trade on the stock exchange.

Here is a link which has the names for tttk https://money.tmx.com/en/quote/%5ETTTK

What mind of jobs are you looking for? Like infrastructure related or more software development? Maybe check levels.fyi as they have a decent filter?
