I guess the warrant issue is as clear as mud. I read the Laws as stated in e-laws.
1.A conservation officer may obtain a search warrant under Part VIII of the Provincial Offences Act .
2.If a conservation officer believes on reasonable grounds that there is in a building or other place any thing that will afford evidence of an offence under this Act but that the time required to obtain a search warrant would lead to the loss, removal or destruction of the evidence, the conservation officer may, without a search warrant, enter and search the building or other place.
3.A conservation officer who is lawfully in a building or other place may, without a warrant, seize any thing that he or she believes on reasonable grounds,
(a) has been obtained by the commission of an offence under this Act;
( has been used in the commission of an offence under this Act;
© will afford evidence of the commission of an offence under this Act; or
(d) is intermixed with a thing referred to in clause (a), ( or ©.
4. ( that entry to the dwelling has been refused or there are reasonable grounds to believe that entry will be refused.
I guess YES they need a warrant BUT if they believe they need one they would have had it already...
and if they don't have it already their arses are covered......so I guess in the long and short of it they don't really need one.
