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
