Are you sure you don't mean galvanized iron pipe ? I've replaced a lot of that over the years because the scale builds up inside and narrows the I.D. of the pipe down to about 1/8". LOL .... the brass / galvanized connections are even worse !
They outlawed galvanized for use in water & fuel piping about twenty years ago because the zinc coating inside was flaking off and causing health problems.
Those two kinds of pipe do look similar.
Lead service pipes were very common in Ontario for houses built before the 1950's. This was probably the case throughout North America. The attached link gives the mitigation strategy for the City of Toronto. There is so much of the stuff out there that replacing it all a once wouldn't be doable (or affordable).

I wasn't aware of the health risks of galvanized pipe. I always thought they were being phased out because they would corrode from the inside out and fail without warning. I guess it's just one more thing to add to the list of problems associated with old houses. I hate working on them. You never know what you're going to run into.
