The maximum length of this kind of probation is, afaik, set by provincial labour law and is 3 months in all but three provinces (nb, pei, and the Yukon). Employers can go lower, but not higher.

Though I think they can withhold benefits for longer than that separately from the probation period, but that's kind of rare I think.

Really withholding benefits in Canada is pretty different than in the us, though, since here it means you don't buy glasses for three months and there it means you'd better not break your legs.
