Guss---non-residents hunting moose in Ontario must be accompanied by a local guide.
Here is the web page for the MNR--you can find the regulations within:-
http://www.mnr.gov.on.ca/MNR/pubs/pubmenu.html
However it is a lot easier getting a tag to hunt Moose in the maritimes, Nova Scotia, New Brunswick, Newfoundland--you should look in that direction first.
Here in Ontario, the 'red-tape' is fatiguing for a non-resident and dosen't offer very much--of course this has NOTHING to do with
us Ontario residents---directions all made by the guys on the "thrones".
As was the case with banning our Spring Bear hunt--and now bears are roaming "urban residents backyards" and still the Government refuses to revisit the law banning the spring bear hunt---the intelligence is OVERFLOWING!!!!!
Wish I could help you more.
