Cameras on Ontario 511 come from multiple sources. Therefore, the camera images are not updated at the same intervals or displayed in the same format.

Carpool Lots

Ideal places to meet up with your pre-arranged carpool partners before entering the highway system. Where allowed, parking is permitted for a maximum of 120 consecutive hours, unless otherwise indicated by signs. Selected lots are also served by public transit. 


Construction includes information about major construction projects on provincially owned roadways.


Ontario 511 Ferries information includes provincially and privately owned ferry locations. For information regarding specific ferries please visit the websites provided on the Ferries Text Report.

Forecasted Driving Conditions

Forecasted Driving Conditions are based on weather forecasts and pavement temperatures, and are independent of reported road conditions. Forecasted Driving Conditions are identified as “good”, “fair”, “caution” or “poor” based on wind speed, rain, snow, and temperature. Forecasts are generated in four, three-hour timeframes (0-3, 3-6, 6-9, 9-12 hours) up to 12 hours ahead. In addition to Forecasted Driving Conditions, the ministry provides Reported Road Conditions, traffic cameras, and weather cameras to assist drivers in planning their travel during the winter.

Ontario 511 endeavours to provide accurate, up-to-date information, however, Forecasted Driving Conditions are a prediction. Actual driving conditions may differ on occasion.


HOV: High Occupancy Vehicle (HOV) lanes are left lanes restricted to certain types of vehicles carrying at least two people.
HOT: Single occupant vehicles can use these HOV lanes with a permit.

Inspection Stations

Truck inspection stations are found at various highway locations in Ontario. Signs indicate whether or not a station is open. If a station is open, trucks must enter and stop for inspection.

Vehicles and loads are checked for weight, height, length, width and axle spacing. Driver licences are also checked for validity and proper class of licence for the vehicle.
Ontario 511 provides the location of all Ontario Truck Inspection Stations. For road safety purposes, the Ministry of Transportation does not provide an open/closed status for stations.

Remote Airports

Remote Northern Airports are located in Ontario's far north, extending from the Manitoba border on the west to Hudson's Bay on the north and to the Quebec border on the east. Except for Pickle Lake and Armstrong, these airports serve aboriginal communities, which have no all-weather road access to the rest of Ontario.

Rest Areas

Includes rest areas, picnic parks and scenic lookouts.

Road Conditions

Reported Road Conditions are road and visibility conditions reported by the Ministry of Transportation's maintenance contractors. These official reports are generated at minimum, five times a day.
Reported Road Conditions identify the roadway as either “bare,” “partly covered” or “covered” and visibility as “good,” “fair” or “poor.”
Primary Road Conditions are what the majority of the driving surface is like on the roadway/highway.
Secondary Road Conditions are what other condition(s) exist on the roadway/highway.

Short term or emergency road repairs and maintenance on provincially maintained highways: 
  • Current Roadwork includes roadwork events occurring within the next 48 hours,
  • Future Roadwork includes all roadwork events starting more than 48 hours from now.


Roundabouts on provincial highways and ramp terminals are designed to accommodate a regular tractor-semitrailer design vehicle and are not an impediment to truck configurations compliant with O. Reg. 413/05, Vehicle Weights and Dimensions for Safe, Productive and Infrastructure Friendly Vehicles.


Large trucks may need to use more than one lane when they enter, drive through and exit a roundabout. Within the roundabout, they may also need to use the truck apron between the circulatory roadway and the central island. Drivers are cautioned not to drive beside large trucks when approaching or within the roundabout.
Ontario 511 provides the locations and type (single/multi-lane) information for all roundabouts on provincial highways.

Seasonal Loads / Load Restrictions

Under the Highway Traffic Act the province enforces reduced load restrictions on trucks to protect Ontario's highways during spring thaw, when road damage is most likely to occur. The Ontario 511 website provides both map and text based reports on any seasonal load changes to provincially owned highways.

Waze Reports

Ontario’s Ministry of Transportation has partnered with Waze through their Connected Citizen Program to publish Waze reported information on the Ontario 511 website. This program is a free data exchange between Waze and government entities and private road owners and operators.

Waze is the world’s largest community-based traffic and navigation app. Waze gathers crowdsourced real-time traffic data and road information from its users. Waze incidents, standstill traffic jams and weather hazard data identified by the Waze app are now available to view on Ontario 511. This information is provided in addition to official information reported by the ministry to better help people plan their travel in Ontario.
