"...Is a guide required for non resident hunting..." Yep, but it depends on the WMU. A non-resident landowner is treated like any other non-resident.
"Most non-residents hunting bear in Ontario will be required to use the services of an operator (a tourist outfitter, guide, or air operator) licensed to provide black bear hunting services to non-residents."
"Non-residents must be accompanied by one licensed guide for each two hunters when hunting deer in the Territorial District of Rainy River. WMUs within the Territorial District of Rainy River are 9B, 10, 11A and part of 7B and 12B."
"Non-residents must be accompanied by one licensed guide for each two hunters when hunting moose in the Territorial District of Rainy River. Wildlife Management Units (WMUs) in the Territorial District of Rainy River are: 9B, 10, 11A and parts of 7B and 12B."
"A non-resident who wishes to hunt moose in Ontario must have valid hunting accreditation and be a registered guest and actually accommodated at a tourist establishment."
"Non-resident moose hunters may hunt moose in WMUs 7B, 9B, 11A, 11B, 12B, 13 and 14 only by hunting through a tourist outfitter or by hunting with an immediate relative."
