Your comment is just speculation and it works differently than immigration for tech work between US and Canada. The comments about “blue card” visas are correct. Also, TN visas work for engineers with a four-year degree, do not automatically work for software developers, although you might be able to massage the (probably outdated) job description to include “computer systems analyst”.
