Axle Weight Pilot Project Finished August 26, 2019
The objective of the pilot project was to develop a database that will help standardize the way allowable gross weights and axle weights are collected, stored and used for compliance.
TEMPLATE Letter for Members to Use to Submit Responses to ERO Posting on Growth Plan February 13, 2019
The government has submitted a proposal to make Modifications to O. Reg. 311/06 (Transitional Matters - Growth Plans) made under the Places to Grow Act, 2005 to implement the Proposed Amendment to the Growth Plan for the Greater Golden Horseshoe, 2017. OSSGA has made the point to the government that the current policy framework is not working. Approvals for new mineral aggregate operations in Southern Ontario are taking up to 10 years to complete the process. There are too many overlapping policies and inconsistent approaches between the Provincial Plans, Regional Official Plans, Local Official Plans and Conservation Authority policies regarding the management of this essential non-renewable resource.
Specification Alert February 6, 2019
Please be advised that there have been changes made to Aggregate Specifications for OPSS 1002, April 2018. This revised specification has been included in several MTO tender documents recently, most notably MTO Contract #2018-2024, Hwy 400 & Hwy 89 Interchange, Closing Feb. 14, 2019 and has raised concerns with many suppliers.

Axle Weights Update

July 5, 2016 at 3:42 PM

Phase 2 of the enforcement of axle weights by the Ministry of Transportation (MTO) will begin again on August 1st, 2016.  As a reminder, there has been a moratorium since 2014 on the enforcement of axle weight issues as OSSGA and MTO develop a solution to the issue.

Therefore, there have not been any charges laid at the inspection stations -- just warning tickets. This will change on August 1 as the moratorium ends.

Phase 2 will run from Aug 1, 2016 –March 31, 2017 and will consist of new enforcement thresholds and a new interim axle weight charge and detain for correction level. Charges will be issued and vehicles will be detained for correction when axle or gross weight exceeds the specified thresholds.  These new levels are detailed in the attached chart of enforcement. All configurations of trucks will be affected by these changes, so please review the chart to better understand how it will affect you specifically.

OSSGA continues to drive for a resolution to this issue and has been working with MTO for the past few years; we are hoping that we will be able to move forward with a solution in the near future. 

In anticipation of this change, OSSGA recommends that members take all necessary steps to prepare.  As always, the maintenance and calibration of load equalization systems remains vital.  Finally, trucks should have white sheets made up by the MTO to ensure accuracy when crossing the scales. 


Summary of Issues for Aggregate Shippers: 

Knowing what to load on a truck

  • Dependent on carrier to provide a document
  • It is vital that shippers understand all the variables before loading (SPIF, GVW, etc.)
  • Knowing what weight is achieved on the front-axle.

Data shows that little weight is transferred to the front steering axle on tractor semi-trailers.

  • Knowing whether the truck can load equalize properly


As August 1st approaches it is important to:

Communicate the change to the trucking community

  • Enforcement dates
  • Have drivers calibrate & do maintenance on load equalization systems.
  • Get proper “White Sheets” Gross Axle Weight (GAW) done by MTO
  • Adjust loading practice of put more weight to the front.
  • Better to evenly distribute load
