there has only been one griz sighting in manitoba, and that was right at the tree line south of churchill, mb. that bear was sighted and confirmed a griz by the manitoba dnr, and it's theorized that it was probably from northern alberta or b.c. and just kept wandering east. there have been no confirmed sighting since. As a follow-up, I called the kenora dnr office (since it's only a couple hrs away from winnipeg) and spoke to a c.o. I gave hin the link, he looked at it, laughed and said" if that was shot in ontario, that hunter would have been charged on the spot for poaching.
John C. is right... there is no spring season for bear.
