There are parts of the US that are in the US and don't produce quite as many actors and music artists. Though there are some other factors (e.g. Vancouver's generous film subsidies and variety of cool-looking architecture to use as outdoor film sets), there seems to be way more Canadians in entertainment than you'd expect, and I wouldn't dismiss the influence of Can-Con regulations.
Of course, it probably helps that Canada has plenty of cultural and linguistic similarities to the United States. Preserving the native culture of, say, Denmark through Danish Content regulations on popular entertainment means producing content that isn't easily consumed outside of Denmark, whereas a ton of Canadian Content can be easily marketed in the United States.
