(b) after doing so, believed on reasonable grounds that his or her obligations were being complied with.
Note: In a prosecution for an offence of strict liability against a provision of this Act or the regulations, a defendant bears a legal burden in relation to the matters in this section (see section 13.4 of the Criminal Code ).
