TORONTO, Ont. – The city is calling for sustainable and creative proposals for the future of the Toronto Zoo.

The city manager’s office issued a Request for Expressions of Interest on Monday that encourages ideas for innovative and sustainable business models for the east-end zoo.

The request also asks respondents to consider plans that include the Rouge National Urban Park, which resides next to the zoo.

A review committee comprised of city staff, the Toronto and Region Conservation Authority and Parks Canada will review the responses.

The city manager will make a recommendation regarding the next step to the executive committee and city council. A report from the office is expected next spring.

City council will make the final decision regarding what outcome arises from the submissions.

The city will accept proposals until Nov. 26.
