Battle over 24-metre sports dome at Markham’s St. Augustine moves to Ontario Land Tribunal
By Gene Pereira, Local Journalism Initiative reporter
A contentious battle over a proposed multi-million-dollar sports facility at a Markham catholic high school is heading to the province’s highest land-use tribunal.
The York Catholic District School Board (YCDSB) and its private operating partner have officially appealed to the Ontario Land Tribunal (OLT) after the City of Markham’s Committee of Adjustment rejected critical zoning variances for a massive air-supported dome at St. Augustine Catholic High School.
The appeal, submitted on August 10, comes after weeks of local pushback regarding the sheer size and municipal non-compliance of the planned facility. Designed to offer year-round training space for both high school athletes and community sports leagues, the project has instead pitted school administrators against nearby residents and city officials who argue the structure simply does not belong in a residential neighbourhood.
Located near the intersection of Woodbine Avenue and 16th Avenue, St. Augustine Catholic High School was slated to become the latest YCDSB campus to host a large-scale, private-partnered athletic facility. Similar arrangements across the board have proven popular, including the 100,000-square-foot Woodbridge Sports Dome at Holy Cross Catholic Academy.
According to the school board, the St. Augustine project is meant to fill a critical gap in local athletic infrastructure by providing student athletes with all-season access to indoor fields, while offering the broader Markham community additional recreational space.
However, the physical realities of the design ran into immediate regulatory roadblocks at City Hall. Markham’s Committee of Adjustment formally denied the project’s minor variance application on July 22 after identifying three major conflicts with local zoning bylaws, including its height, setbacks, and parking restrictions.
With a peak height of 24.08 metres, the air-supported dome far exceeds the city’s maximum limit of 15 metres for indoor sports facilities. The Dome will also sit just 21.57 metres from residential property lines along its northern side. The submitted plan also included only 234 parking spaces. Municipal zoning requires 479 parking spaces for an athletic facility of this capacity.
The Dome proposal raised immediate concerns from several neighbourhood residents, who submitted letters of objection ahead of the July vote.
Areas of concern expressed included the size of the 24-metre structure. Saying it would tower over single-family homes and block views. Noise and the proximity to residential backyards on the northern side were other key issues.
Frustration also grew over what residents described as a flawed public notice process. Initial mailings distributed by the city lacked detailed blueprints, forcing concerned neighbors to go door-to-door across the subdivision to share information and organize opposition ahead of the committee hearing.
Markham Ward Councillor Andrew Keyes noted that while the municipality values athletic investments, the commercial nature and physical scale of the dome created an undeniable friction with the surrounding community.
“We certainly, as a city, welcome these kinds of installations. It’s just that they need to be put in the appropriate place,” Keyes said. “It’s fairly clear what the issues would be with the City and what the neighbouring residents are concerned about, more than likely the visual impact it would have on the neighbourhood.
“Often, it’s also concerns about parking and traffic. The City’s decision was really based on the interests and appropriateness relative to the surrounding area.”
Keyes emphasized that the commercial aspect of the partnership changes the dynamic of what is typically expected on school grounds.
“And when you get to a commercial facility, which is what this would be, there are zoning restrictions that are in place for pretty good reasons,” he explained. “It’s usually to protect the use that’s intended for the immediate area, and, in this case, residential.”
He added that the school board’s participation was essential for the project to even reach this stage.
“They wouldn’t be able to do this without the support of the Catholic School Board,” said Keyes. “This is just a situation where the city and the residents aren’t comfortable with that design.”
By lodging their appeal on August 10, the YCDSB and its private partner successfully bypassed the municipal council, shifting the final decision-making power from local authorities to a provincial body.
The move leaves municipal leaders and local homeowners preparing to take their case to a provincial hearing.
“Obviously, a decision by council can be appealed, and that’s what they’re doing, and it’ll be out of our hands once it goes to the OLT,” Councillor Keyes said. “The OLT will have its opportunity to apply its discretion, and residents that are opposed would certainly be invited or welcomed to express their concerns at the OLT.”
Keyes expects Markham will defend its original decision to uphold local zoning standards.
“I’m not sure yet whether the city will be represented, but it’s quite likely that the city would send representation as well to defend our position,” he said.
A date for the Ontario Land Tribunal hearing has yet to be scheduled.
