I'm not very familiar with the requirement of the tech pilot, so I can't be absolutely certain - but my initial impressions based on reading a little bit is that this could make a difference. The eligibility requirements don't mention that your employer
must have paid all their taxes, but the general employer requirements listed here -

state that the employer must
"have a history of good workplace and business practices.
Your employer must be financially sound and have a history of good workplace and business practices, including complying with all applicable B.C. and federal employment, labour, immigration, health and safety laws and regulations. Your employer may be asked to provide financial statements prepared by a certified professional accountant."
I'm not sure whether not paying taxes means that your employer isn't complying with B.C/Federal law.
Perhaps someone with more knowledge can help.
