No, not stab-lok thingies.

It's a Novaline cabinet, with Westinghouse breakers that clip firmly onto the power rails. I forget the name for the exact connector style, but not stab-lok.

I put it in myself back about 23 years ago.

Edit: I think the current replacement breakers would look like this one: http://www.homedepot.ca/product/plug-in-duplex-quad-replacement-breaker-1-1p-15a-1-1p-30a/943174

Be happy it's that way. My house essentially had everything on one breaker. Over the years I've added breakers with associated conduit running around the outside.

I'm surprised you don't have the basement workshop on a sub-panel...

One of my regrets. Never thought the 40-breaker panel would fill up -- the original old fusebox had only 12 fuses. Oh well.

However, I have identified a couple of circuits that can be combined onto a single breaker (while still totalling 12 or fewer devices), so I may yet re-plumb things there for a whole house surge suppressor.

Cheers
