This is the Answer from the FAQ section of Nutiva. Our hemp is sourced from Canada as well.
Q. If I recently consumed hemp foods, could I fail a drug test?
A. If the only source of the psychoactive THC in your body is from hemp foods, produced from Canadian grown hemp seeds and eaten in reasonable quantities, it is virtually impossible to fail a drug test by ingesting hemp foods due to the fact that THC levels in our products are barely measurable.
I'm not sure who answered the Q, however this aligns with what I've heard elsewhere. We have not tested this so we cannot say for sure. This Q may be better addressed with your Dr.
