Another reason for NOT heating in winter is to prevent ice dams.....you will see IF the soffits are vented properly the earliest snow next year, watching the "heat loss patter" above the garage.    Just guessing but "do you even have gutters!"    I know up north MI they eliminate them for this reason !

Seeing you are in Canada , I'm sure you have colder/longer periods so it really comes down to a comparison of cost.  My wife keep asking "what is it costing to heat 3 garages?"  and I say NO MORE then your cost difference to buy VEGAN food!
You are absolutely correct about ice dams.  Had an issue with them over a portion of my work area next to my garage bays as the sun never really hit that portion of my roof.  Had a commerical company install air baffles & ceiling insulation.  No help.  Went on line to learn about ice dams.  Reevaluated and attacked the problem myself.  It took me 2 months working by myself, but I removed the ceilling insulation blankets and then the plastic baffles.  Next I build a complete air channel between each ceiling joist.  Using 1" thick foil one sided styrofoam I cut 2"high by 4' long strips and nailed one to each side of the joists next to the roof, then I cut a "lid" same width as between each joist 4' long and pinned/glued this lid on top of the 2" high side strips to form a complete air channed from my gutter soffits to the roof peak that is vented.  Next I chalked all the seams and reinstalled the ceiling insulation over top of these new air channels.  Really pleased as this winter when it snowed, the snow now laid evenly across my roof.  NO ICE DAMS!

Tongue Do you not think that heater is a bit big for a rear window defogger!

Looking good now to just drill a natural gas well in your back yard. 
It was a very mild winter here in NC. We only had a couple 2" snows that were gone the next day. The ground never really froze first time I have ever seen. It never got below 45 deg. in my 4,000 sq. ft. garage with one hot oil electric heater of 1,800 watts not on high. 
I did build a seperate work room that is very easy to heat. The garage has 6" of fiberglass, foam filled doors and dual glazed gas filled insulated windows. 
I built the work room inside the garage. it has 6" walls with staggered studs so the inside walls do not connect to the outside walls. The ceiling is 2" X 12" with 12" of fiberglass in there also. 1/2" drywall. I also put a 45 deg. angle around the inside to mount work lights and to get rid of the dead air space. I think body heat would heat it, lol. 
I had bought a gas heater and have never put it in for four years not never has really got cold. 
I am probably going to put a very small window unit heat pump in the work room so I can also cool in the summer. 
Just a hint. My guy that erected my building gave me all the cut outs from doors window and such and there was also a couple extra rolls. He said if I needed more he would give more to me. He has to pay to put in the dump there is always lots of scraps and extra. If you are wanting to insulate your work area check with someone that erects large steel buildings and offer to clean up the scraps for free. 
In the old one car garage I had a wood heater to get it jumped started after I lit I would take my cutting torch and turn on the oxygen and blow in the draft and it would be roaring in seconds, lol. I use to do body work during the winter and paint when it got warm enough in there.


When a man is in the woods and talks and no women are there is he still wrong??

Nice!  I wish my garage could support a lift, because I'd really like to justify putting HVAC in there as well.

Lookin' good!  Hope it works how you want it to.  thumb


Gotta really question the Cowboys sticker, though.   Shootself
