I don't think so. Even though Niagara Region is adjacent to Buffalo, there seems to be relatively little commuting between the two. According to Statistics Canada (2006), only 1.0% of Niagara's labour force works outside Canada compared to 79.5% working within Niagara Region (including at home), 10.5% elsewhere in Ontario (like Hamilton), 8.7% with no fixed workplace address, and 0.1% in another province. Niagara Region would qualify being its own MSA (though as I said, might qualify for Toronto-Hamilton's CSA.
I wonder what the numbers for Northumberland and Haldimand/Norfolk and Perth are. According to the 2006 census.
38.9% of Haldimand's workforce works outside Haldimand
26.1% of Northumberland's workforce works outside Northumberland
24.1% of Norfolk's workforce works outside Norfolk
15.4% of Perth's workforce works outside Perth
That doesn't say where they commute out to though. Do Norfolk residents commute mostly to Hamilton? Brantford? Maybe even London? Or Niagara Region? That's why the Transportation Tommorrow Survey is good, but unfortunately it only covers the Golden Horseshoe.
