Every electrical-era Sudbury house that doesn't have a Federal Pioneer panel had to have something else — and Panel Upgrade Sudbury built this page because "something else" is frequently a brand with its own underwriting problem. Here's the full watch-list.
Commander / Sylvania / CEB — the Canadian second family
Commander panels — sold under Sylvania branding on many doors and related to equipment badged CEB — were mainstream Canadian hardware from the mid-1960s into the early 1980s. That window sits squarely on Sudbury's biggest building decades, so the stock here is real: the same New Sudbury, Valley and Chelmsford streets that got Federal Pioneer panels got Commander panels next door.
The documented issue is different from Stab-Lok's but rhymes with it: electrical-safety writeups (The Shock Doctors and Canadian home-inspection references among them) describe bus-bar alloy that deteriorates over roughly two decades, degrading the connection where breakers seat — plus breakers that can fail to trip. Certified replacement breakers exist but are priced like antiques, which makes a full panel swap the economically rational fix — exactly the conclusion insurers have reached, which is why Commander and Sylvania now appear on renewal questionnaires alongside Federal Pioneer.
The occasional American strays
- Pushmatic / Bulldog — push-button breakers with no visible handle position; flagged in inspection literature for sticking and hard resets. Uncommon in Sudbury but they exist in mid-century stock.
- Challenger — a name inspectors flag on certain breaker series; mostly a US installed base.
- Zinsco — thin in Canada, notorious in US inspection writing for bus-bar burn; if a label says Zinsco, treat it exactly like the names above.
Cost and the same bundle logic
A Commander or Sylvania swap runs $2,000–$4,500 depending on condition and circuit count — the full table is on the cost page. And because these panels overwhelmingly sit on 100-amp services in 1965–83 houses, the 200-amp bundle argument applies with full force: the utility disconnect and labour are being paid for once, and these are precisely the houses now adding EV chargers and heat pumps.
