The textbook I read to study for my provincial Engineering Law and Ethics exam had a section on non-competes. It straight up said the vast majority of non-competes are not enforceable but warned that the more specific the circumstances described by the non-compete the greater the chance that a court would enforce it. The example they used for something that would most likely be enforced was a geologist working for company A doing a mining survey in a area under a 6 month non-compete cause would definitely not legally be allowed to take a job for company B to do a survey in the same area until the non-compete expired.
