Hi Mark,
Your frame is from 1976. The Shields name on the down tube. Shields was the Canadian distributor in the late 1970s.
I have seen pictures of US market Internationals from the late 1970s and their frames say "Chrome Molybdenum". I don't know if people were using the term "4130" in the late 1970s.
Given the era and Canadian market, this International is probably hi-tensile steel, The database shows a similarly spec'd, 1977 Shields Nishiki International with a hi-tensile decal. Baring a decal, the best way to identify the frame material is via the seat post diameter.
