Canadian holding procedures

....
That's it - no more, no less. On the missed, you either talk to ATC
(or you follow lost comm. procedures) or you are uncontrolled and on
your own.

That is a good point (many people who learned to fly IFR in the lower
48 and southern Canada don't think of it that way, but the airspace
system is designed to allow instrument flight from takeoff to
touchdown without ever talking to anybody). But I think the
discussion was not largely misunderstood, the basic question was what
is the clearance limit at the end of an IAP in *controlled* airspace,
and besides Frank's reference to the AIP, this has gone unanswered.
Is it the MAP, at which point you enter either a published or standard
holding pattern, or the alternate airport ?

Sorry, not to nit-pick, but this is a real scenario - I just missed an
approach, got busy reconfiguring the airplane and I am reaching the
"climb-to" altitude 0.5nm from the MAP with its *depicted* racetrack
pattern at 120 knots. The frequency is congested and I can't get a
word in. What should I do in Canada ?
