From the IAAF:

Organisers of the Scotiabank Toronto Waterfront Marathon have been awarded IAAF Gold Label Road Race status for the first time in its history. The 2015 race will take place on 18 October.

The Toronto race is the sole Canadian marathon to achieve this level and only the fourth in all North America. Boston, Chicago and New York are the other IAAF Gold Label Road Race marathons in this part of the world.

The announcement was greeted with elation by the 15 full time staff in the Canada Running Series office, who have worked tirelessly to improve upon the Silver Label the race has held for the past seven years.
