That is the cat which ate the canary
The cat that ate the canary
The cat who ate the canary
I am concerned that he's not going to show for work.
That which is too ugly to think about.
When do you use "That" and when do you use "which"?
I use "that" for restrictive clauses only and "which" for non-
restrictive clauses, immediately after prepositions (which is a
construction that I seldom use), and in "that which" (to which I
almost always prefer "what"). Many people also use "which" for
restrictive clauses.

A short explanation would be incomplete, and probably misleading. Any
book on English grammar will devote several pages to this topic.

I agree with the other answers. I would like to point out, though,
that your second-last example, "I am concerned that he's not going to
show for work," uses "that" as a conjunction, not a pronoun. It's a
different word from the pronoun that you might confuse with 'which".
This one depends on what you mean. I guess you are thinking that
we know that some car caused the problem and the question is whether
*this* car is the one that did it. In that case "that" or "which"
is a relative pronoun, which is like a conjunction but also refers
back to "the car" as an antecent. Since the clause is restrictive,
both versions are correct, but the "that" version is usually preferred
and some people will see the "which" version as wrong.
On the other hand, maybe there is only one car and you are asking
whether it caused the problem or something else caused it. In that
case only the "that" version is correct. This is a different sense of
"that", where it is just a conjunction and does not refer to the car.
In either case the question would usually be asked with "is it"
rather than "it is", but "it is" is possible if you think the answer
is yes and you are asking for confirmation.
> That is the cat which ate the canary
> The cat that ate the canary
Again, "that" or "which" is a relative pronoun and the clause is
restrictive. Both versions are correct, but the "that" version is
usually preferred and some people will see the "which" version as wrong.
> The cat who ate the canary
If you use this, you are treating a cat as a kind of person.
Cat-lovers might say this; other people would not.
> I am concerned that he's not going to show for work.
Correct. "That" is a conjunction in this sentence.
> That which is too ugly to think about.
Here, "that" is an ordinary pronoun (with no antecedent) and "which"
is a relative pronoun with "that" as antecedent. Again the clause
is restrictive, so "that" would be correct instead of "which" (that
is, you could say "That that is too ugly..."). But here, most people
who would say this at all would prefer "which" in order to avoid the
repeated word.
> When do you use "That" and when do you use "which"?
This is not a simple question.

Hunh? The word "that" is a relative pronoun in both cases. The
difference, as I see it, is between "it" as a regular demonstrative
pronoun in the first case and "it" as a dummy subject in the second.

Oops, so it is. I don't think I would ever use "which" in that version
of the sentence, but on thinking about it again, it is possible to do so,
and so it clearly is a relative pronoun after all. I retract the paragraph.
I was thinking of "that" as used in
"Is it (true) that the car caused the problem?"
where it really is just a conjunction. Sorry.
