Most provinces upgrade services for EVs; Nova Scotia upgrades them to get off oil. A large share of HRM's housing still heats with fuel oil — the same era stock Halifax Panel Upgrades covers for aluminum wiring and flagged panels — and every oil furnace that leaves for a cold-climate heat pump moves the home's biggest energy load onto the electrical service. Add the hot water tank following it, the induction range replacing propane, and a Level 2 EV charger somewhere in the next decade, and the 100-amp service that was generous in 1974 becomes the bottleneck for the whole plan. The 200-amp upgrade is how HRM houses make room.
The load math, without the mystery
Whether you need the upgrade is not a matter of opinion — the Canadian Electrical Code load calculation answers it from your square footage, heating type and fixed appliances. As rough orientation: a cold-climate heat pump with electric backup can claim tens of amps, an electric water heater draws more than most kitchens, a Level 2 charger is a sustained 30–50-amp appetite, and an electric range holds its classic double-digit share. Two of those on a 100-amp service is a squeeze the calculation may still bless; three usually isn't. The partner electricians run the calc as part of the quote and will tell you plainly if 100 amps still clears — it sometimes does, and this site has no interest in selling capacity a house won't use.
What the upgrade physically includes
- New service mast and attachment hardware rated for the heavier conductors
- New meter base — HRM's coastal air corrodes these; replacement is standard practice during any service rebuild
- 200-amp service conductors from the mast to a new 40-plus-space breaker panel (Schneider, Siemens or Eaton), every existing circuit transferred and labelled
- Grounding and bonding rebuilt to current code
- The NS Power disconnect and reconnect, the wiring permit, and the final inspection
Cost guides for Halifax put panel-and-service work at $2,200–$5,300, with full 200-amp rebuilds toward the top of that band and one Canadian guide citing roughly $5,000 average with parts and labour. Line items and what moves them are on the cost page.
If your panel is on an insurer's list anyway, the decision is nearly made for you. A Federal Pioneer or Commander/Sylvania swap already pays for the permit, the disconnect day and the electrician's setup. The additional cost to come out of that day at 200 amps instead of 100 is the cheapest capacity you will ever buy — and doing it separately later means buying the whole day again.
One day, choreographed
The sequence is identical to the 60-amp rescue because it's the same rebuild at a different rating: permit opened with NS Power, disconnect booked, old service equipment down and new equipment up between morning and late afternoon, inspection, reconnection, dinner cooked on the new panel. In Nova Scotia the inspection isn't a third party to chase — NS Power is the inspection department, so the utility that reconnects you is the one that signed off the work. Details on the permits page.
When 200 amps is the wrong answer
Honesty clause: a well-insulated bungalow keeping its oil or gas heat, adding one mini-split and no EV, will likely pass its load calculation at 100 amps for years. If the panel is healthy and unflagged, that homeowner should spend nothing. The upgrade earns its cost when loads are stacking (conversion projects, additions, secondary suites) or when flagged equipment forces panel work anyway — which, in HRM's 1960s–70s belt, is most of the calls this site gets.
