Yes, and that lists, if you want, includes "outdated" timezones as well:

derick at whisky:/tmp $ php -n -r 'var_dump( timezone_identifiers_list( DateTimeZone::ALL_WITH_BC ) );' | egrep '(Montreal)|(Toronto)'
  string(16) "America/Montreal"
  string(15) "America/Toronto"

PHP keeps the old "deprecated" entries as well, so I'm not sure what 
you're asking. America/Montreal works just as well as America/Toronto:

derick at whisky:/tmp $ php -ddate.timezone=America/Montreal -r 'echo date("Y-m-d H:i:s e O");'
2016-04-18 11:23:03 America/Montreal -0400

derick at whisky:/tmp $ php -ddate.timezone=America/Toronto -r 'echo date("Y-m-d H:i:s e O");'
2016-04-18 11:23:11 America/Toronto -0400

cheers,
