In Manitoba you can use a ML during the regular rifle season. There are areas that are bow and ML only and many during rifle do not hunt these areas because they are out with their center fire guns. It's amazing what comes out of the bush in the non-rifle areas during this time. It's like the deer think the season is over and are just walking around stupid esp. in the third week of the regular season (since there is little to no hunting pressure for a couple of weeks). Hey if it is legal in your province or state...give it a try.
