Électrifier les parcs de véhicules moyens et lourds

The report identifies the electrification of medium- and heavy-duty vehicles (MHDVs) as critical for Canada's 2050 net-zero goals, noting that this sector lags behind light-duty vehicle adoption. It highlights three primary obstacles: limited vehicle supply from original equipment manufacturers (OEMs), charging infrastructure and grid capacity constraints, and high upfront capital costs. To address these, the document proposes catalysts including the development of short-term corporate action plans, the alignment of utility planning with decarbonization trajectories, the implementation of zero-emission vehicle (ZEV) sales mandates, and the creation of innovative public-private financing models.

• Transport is the second largest source of greenhouse gas emissions in Canada by activity sector, and meta-analysis indicates that electricity must become the primary power source for most or all Canadian road MHDVs by 2050 to reach net-zero.
• The federal government intends to mandate that zero-emission MHDV sales reach 35% by 2030 and 100% by 2040 for a specific sub-category of vehicles, aligning with a Global Memorandum of Understanding signed by 14 other countries.
• Three main barriers hinder MHDV electrification: limited OEM manufacturing capacity leading to long waitlists, uncertainty regarding who pays for and implements electrical grid and charging infrastructure upgrades, and high initial capital expenditures compared to internal combustion engines.
• Utility providers must shift from reactive capacity planning to proactive alignment with net-zero trajectories to ensure sufficient clean energy and grid capacity for MHDV fleets, including supporting megawatt-scale charging for long-haul trucks.
• The report advocates for federal and provincial ZEV sales mandates to provide market certainty for both OEMs and fleet operators, citing California's Advanced Clean Truck (ACT) regulation as a leading North American model.
• To overcome high upfront costs, the report suggests public-private-Indigenous partnerships to create innovative financing products, particularly for specialized vehicle classes and public charging infrastructure where the business case is weaker.
