“Fitz was successfully immobilized, and our Animal Care, Health & Welfare team safely relocated him to his back-of-house space. There were no injuries to guests, staff, volunteers or animals,” read the email.

The zoo opened to the public shortly after 9 a.m., however the Wild Canada section of the zoo where the grizzly bear enclosure is located remained closed while a “full assessment of the area” was completed. The area was reopened to guests early Sunday afternoon.

“Our teams will be reviewing the circumstances of the incident as part of our established post-incident procedures. We do not have any further information to share at this time.”

Fitz is one of two cubs that were orphaned last fall near Diamond Valley that made their public debut at the Wilder Institute’s Calgary Zoo back in May.
