The lead
Onyx to add 315 rental homes in Downtown West

Downtown West is set to get 315 new rental homes through Onyx, a mixed-use purpose-built rental development by Cantiro. The project marks the first development under Calgary’s demolition incentive plan.
The development combines purpose-built rental housing with mixed-use space, putting a sizable residential project into Calgary’s Downtown West pipeline. Cantiro is the developer behind the project, which is being advanced through the city’s new incentive approach rather than as a standalone conventional rental build.
For GCs and trades, the headline number is 315 homes in one project, alongside the mixed-use component. Onyx is the first project identified under the demolition incentive plan, making it an early test of how the program moves older properties toward new rental construction.
