Throwing out some random thoughts...
I'm too lazy to do KM and CAD conversions right now...so I'll just talk in general terms. If you're getting ready to spend serious money ($25K+ USD) on a new car and you drive a fair amount, then spending a little more on an EV is worth considering. An EV will cost more than an internal combustion engine (ICE) vehicle...but if it's not that much more than it could be the better financial move to get an EV at this point (your numbers seem to back that up). I wouldn't buy a new ICE vehicle right now without running the numbers against a comparable EV like you are doing. It's hard to beat a new $10,000 USD Mirage, but I'm not sure we'll ever see those again.
Assuming that an EV makes financial sense on paper, let's put figures aside and talk EV reality for a minute.
How cold does it get there in the winter? EV range...well...it can suck in the winter. In some cases your battery range will be cut nearly in half. That 260 mile range EV might be down in the 130 mile range on colder winter days. Some EVs consume a lot of energy for cabin heat. Heated seats and heated steering wheels will keep you warm and use much less power than constantly heating the entire cabin. So if you would normally not care about those options, they are almost mandatory on an EV in a place with cold winters.
Do you have a garage? Again...it would make life a lot easier for you in the winter.
Do you have a place to charge an EV on your own property...or will you rely on commercial charging facilities? In the US, commercial charging stations charge roughly 3-4 times more for electricity compared to what you would pay for it at home. That will change your EV fuel cost over time.
Do you have a 240 Volt outlet to charge at home...or will you be limited to using a 120V outlet for charging?
What distances do you typically drive in a day?
I don't know what the car market is like in Canada. In the US, a used Mirage is worth more than ever. But almost every new EV (if you can find one right now) is MSRP. So any gain from the sale of your Mirage may be lost when you have to pay full sticker for an EV to replace it. Your EV govt incentives are higher up there...which works in your favor.
