Company Profile

Established in 1962, Maritime-Ontario Freight Lines Limited (M-O®) is proud of its rich history and excited about the key economic role transportation plays in Canada and the United States. 

M-O's roots began in Nova Scotia, providing Less than Truckload and Truckload service between Atlantic provinces, Quebec and Ontario. The company expanded the network into Western Canada to establish a comprehensive terminal network coast to coast.

M-O has been at the forefront of the Canadian industry through developing innovative methods of transporting freight such as our revolutionary FreightWorks system of loading palletized freight.  This system enables higher load factors and virtually eliminates shipment damages, translating into higher efficiencies for our customers.

M-O has evolved, creating multiple divisions that provide maximum flexibility and commitment to not only meet customer's demands, but to exceed them - no matter what!

Our six operating divisions include M-O FreightWorks, M-O COLDchain, M-O DedicatedWorks, M-O PaperXPRESS, M-O LogisticWORKS, and BULK Services.

Maritime Ontario's quest to continue to expand our capabilities to enable our customers to grow their business, has resulted in establishing a service partnership with one of the largest carriers in the United States.

Innovation has been a cornerstone at M-O for half a century, our future is extremely positive as we continue to provide our customers with the most effective solutions for the next 50 plus years.


Facilities & Equipment

Maritime-Ontario's state-of-the-art facility in Brampton, Ontario is the flagship of the network.  It features, 96 truck level doors and 3 drive in doors, located on a 65 acre site adjacent to CN's Intermodal, and in close proximity to CP's Vaughan Intermodal Terminal.

The dock is 127,000 sq ft long by 170 ft wide, an innovation enabling 53 ft trailers to be offload simultaneously allowing efficient load sequencing to maximize the cube of each trailer.

The high security yard has parking capacity for more that 400 trailers.

The facility also contains 42,000 sq ft of office space, home to our head office functions.

M-O is consistently updating and increasing the capacity of the fleet with late model tractors, trailers, and intermodal containers.  Majority of the trailers and containers are equipped with reefer or heater units. l

Intermodal containers are also equipped with our FreightWORKS captive beam system, allowing double and triple stacking of pallets to maximize capacity and virtually eliminate damages.

Knowing where the fleet is at all times is critical, therefore we have installed both tethered and untethered tracking units to allow us the ability to monitor and change the temperatures of our heated/reefer units.


Eco Green

M-O® Committed to reducing our environmental footprint



M-O is proud to participate in the FleetSmart program in conjunction with the Canadian government's Department of Natural Resources.


One litre of diesel will crate 2.7kgs of CO2 gas. If a truck traveled 3200 Kilometers carrying 27.27 tonnes it would burn 1291.9 litres of diesel fuel crating 3.495 tonnes of CO2.
Intermodal rail would burn 442 litres carrying the 27.27 tonnes over the same distance crating 1.195 tonnes of CO2.

M-O moved 6800 loads via intermodal last year. Based on calculations in the previous slide the net savings in CO2 emissions using intermodal rather then road was approximately, 15,640 tonnes.


Pollution Prevention

M-O recognizes as our company grows so does our impact on the environment. We strive to ensure all employees are aware and do their utmost to minimize the impact of these potentially harmful effects. Minimizing emissions, energy usage and alternative ways of moving freight are entrenched values in all employees.

Minimizing Emissions

  • Making sure all drivers are shutting down their engines when they are not driving.
  • Using bunk heaters for winter months as opposed to idling their engines.
  • No idle policies at all M-O facilities.
  • The use of speed limiters to reduce the amount of fuel consumed and CO2 emitted.

Alternative Ways of Moving Freight

  • M-O’s Logistic loading process to maximize trailer utilization.
  • Using intermodal service to reduce the number of trailer moving over the road.
  • Using container vessel to reduce the number of trailers moving over the road.

Energy Usage

  • Lights out policy on all M-O facilities when not in use.
  • Keeping all dock doors closed when furnace is on and doors not in use.
  • Keeping thermostats set a reasonable levels for heat and air conditioning.
  • Utilizing natural light to reduce electricity in buildings.

Proactive Measures

Purchasing equipment that is certified for energy efficiency to reduce the amount of fuel burned on shipments requiring temperature control.
Maintain all equipment on a regular basis to ensure maximum efficiency.
Ensuring proper tire pressure on all units.

Proactive Measures Fuel Savings

  • Cab and Roof Flaring 6%
  • Adjustable Roof Deflectors 2%
  • Trailer Side Skirts 4%
  • Rear Trailer Flaring 1%

All above are designed to reduce the amount of fuel consumed in-turn reducing CO2 emissions.


M-O has developed a process to maximize utilization on all units. Trailers and containers are loaded logistically which increases the total space available by upwards of 40%. If we take an average of 25% this has actually reduced the total number of units shipped on the rail by 2226 and reduced CO2 by another 6,118 tonnes.

There was an additional 3200 units that moved via road. Using the same formula loading logistically has reduced the total number of units shipped by 1066 and further reduced CO2 emissions by 2,880 tonnes. The total reduction in one year was 24,638 tonnes of CO2.


  • As you can see it is the small measures that are making a difference.
  • Engaging everyone in the process
  • Being innovative
  • Encouraging implementation of sound environmental process
  • Minimization of waste in all operations will ensure M-O’s success in reducing our environmental footprint.
