Dear Dr. Simpson:
Thank you for your email regarding the process of hydrocarbon extraction
through the process of hydraulic fracturing or ‘fracking’. While most oil
exploration and commercial production activity in Canada occurs exclusively
under provincial management and regulation, the federal government does
regulate offshore activity and that which takes place in the Canadian North.
Toxic chemicals, however, are under federal jurisdiction and the process of
fracking is understood to involve the introduction of various chemicals
including various acids and abrasives into the targeted rock formations and
is, therefore, very much under federal oversight.
