Building a yurt-like hardwall structure as a permitted dwelling (residence) is going to be a challenge anywhere outside unincorporated townships in Ontario. Most townships have minimum building
footprint rules that you will violate, expensive septic system requirements that will seem out of place for a structure this size, and there will likely be a whole range of Ontario building code requirements that such a yurt will do differently, and so need exceptions, engineer reports, etc. And that's before you even think of installing a
wood stove.
Townships vary widely in their openness and flexibility towards "hunt camps", which are not dwellings but places for temporary sleepover while making recreational use of the land. Some townships disallow them altogether. Some allow them, but heavily regulated. Some allow them, and regulate them less or enforce the regulations less. You might have more success that way. That's where you need to have local conversations.
Some people have taken the position that a (soft-sided) yurt on a removable deck is a temporary structure, and so no need to seek permission to build it. Some townships disagree with that, and others might if they knew about it. Some townships don't allow regular use of temporary structures anyway, or want to permit them too. And at least one township (North Frontenac) hasn't been sure what to do, and has at least mooted the idea that they would insist on a permit for the deck substructure but ignore the yurt (look up Rush-Inglis, yurt, North Frontenac, 2017-2018). I don't know of anyone who has done so, but it feels this whole approach is less defensible for a hardwall, yurt-shaped structure.
Generally speaking, life is easier if there is an established use of the property, and some normal, grandfathered or legally permited/built/inspected structures supporting that use already in place. And then you erect the yurt as an accessory structure.
