I don't know if you're Canadian, but if you are, you'll know there are some marked differences in the development of education, here, in Canada.
Perhaps it is changing in Canadian philosophy, but that is an anomaly more than a trend.
Even if a department doesn't state they require an MA, it's still an unwritten rule. Maybe if, say, your credentials are stellar and you have a reference from "god," you're in the clear. People getting direct entry are a very rare exception, not the rule.
