Our Client
Network
Ontario Snow & Ice Management (OSIM), operating under Great Lakes Management, provides commercial snow and ice management services to a diverse range of organizations and properties across Niagara Region and Ontario.
Syensqo — Years of Measurable Winter Safety Performance
OSIM has provided commercial snow and ice management at Syensqo for seven consecutive winters. The site is a controlled industrial facility. During that period OSIM has been the only external snow and ice contractor on site besides Syensqo’s in-house crews.
Hand crews wear required fire-protective clothing and hard hats. Truck drivers must pass site-specific safety testing before access. Work follows controlled entry rules and is coordinated around live plant operations.
The winter program manages snow and ice across the facility and is intended to reduce slip-and-fall risk. Facility data from the program is available.

City of St. Catharines — Performing Arts Centre
OSIM has provided snow and ice management services for the City of St. Catharines at its downtown performing arts centre for the past eight years.
The site includes one of the more challenging pedestrian areas in downtown St. Catharines: a large sloped walkway leading directly into an extensive staircase. Managing snow and ice on this type of route requires significantly more than conventional parking-lot plowing. The slope, pedestrian traffic, stairs, changing temperatures, and potential for ice formation make consistent winter maintenance particularly important.
Before OSIM began providing winter services, this pedestrian route was closed during winter conditions on a recurring basis. Since OSIM took responsibility for the winter maintenance, the City has been able to keep the route open and accessible through winter, supported by OSIM's ongoing snow and ice management.
For eight consecutive years, OSIM has maintained this challenging pedestrian route through winter conditions, demonstrating our ability to manage areas where accessibility, timing, attention to detail, and consistent ice control are critical.

A Difficult Route That Stays Open
This site demonstrates an important part of OSIM's approach to winter maintenance: the goal is not simply to clear snow, but to maintain usable pedestrian infrastructure throughout winter conditions.
The eight-year service history at the City of St. Catharines Performing Arts Centre provides a practical record of OSIM's ability to manage a challenging combination of slope, stairs, pedestrian traffic, snow, and ice—helping the facility maintain access where winter conditions had previously resulted in recurring closures.
Post Foods — Food Production & Industrial Winter Management
OSIM's role is to manage snow and ice conditions throughout winter weather events, providing coordinated plowing, salting, de-icing, pedestrian-area maintenance, and storm response around an active industrial food-production environment.
Working at a facility such as Post Foods demonstrates OSIM's ability to deliver winter services where reliability, timing, communication, safety, and uninterrupted site access are important considerations.

Tim Hortons locations have unique winter-maintenance requirements. These are highly active, customer-facing properties where parking lots, drive-thrus, entrances, sidewalks, and pedestrian areas need to remain accessible during winter weather.
OSIM coordinates snow plowing, salting and de-icing, sidewalk maintenance, and storm response to help franchise locations maintain safe and accessible properties throughout winter conditions.
Our experience servicing Tim Hortons franchise locations demonstrates OSIM's ability to manage high-traffic commercial properties where accessibility, timing, customer safety, and consistent winter service are critical.
Government of Canada
OSIM, operating under Great Lakes Management, provides services under a contract with the Department of National Defence (DND), Government of Canada.

OSIM's work supporting DND demonstrates our ability to operate within a structured government environment.
Healthcare & Medical Facilities — Niagara Region
OSIM provides commercial snow and ice management services for medical and healthcare facilities throughout the Niagara Region, supporting properties where reliable winter access and pedestrian safety are essential.
Healthcare facilities operate throughout winter weather and often have continuous pedestrian and vehicle traffic. Maintaining accessible entrances, parking areas, sidewalks, accessible routes, service areas, and emergency access requires a consistent and responsive approach to snow and ice management.
OSIM provides coordinated snow plowing, snow removal, salting and de-icing, sidewalk maintenance, and storm response to help healthcare properties remain accessible throughout winter conditions.
