Here's a good US forum;

It would be better to apply for the US visa from his home country.

When he arrives at the point of entry in Canada, border services officer will make sure he meets the requirements to enter Canada.

The officer will authorize his stay by stamping his passport and/or issuing another document.

If there is no stamp, handwritten date or document in his passport, his temporary resident status will expire six months from the day he arrived in Canada.

If he receives a visitor record the expiry date is marked on it.
