Yeah, "god damn it" is considered a swear in a good chunk of the US. American networks censor some pretty tame stuff.
Canada can be a bit silly about things like nudity (more so when it comes to genitalia, but breasts are almost always censored pre-watershed) and certain swear terms ("cunt" is the big one up here, and sometimes "fuck" when used to refer to sex acts, though both are generally left as is after watershed, even on the free networks), but a lot of what gets shown up here would be censored down in the US.
