Please read http://web.cs.ucla.edu/~eggert/tz/theory.html#naming and the 
archives of this mailing list for many (many!) previous discussions 
about the names of timezones.

Specifically: Montreal (like other parts of Quebec) has been in the same 
time zone as Toronto since 1970.  If you need (often) correct timestamps 
before 1970, you may be able to use the data in the `backzone` file, 
though note the comment about correctness in there.

The boundaries used in the tz database are the boundaries of time zones 
since 1970.  While these boundaries are often in the same place as 
political boundaries this is not always the case.
