Prime Minister Mark Carney announced a package of measures on Thursday aimed at building what his government called a stronger, more resilient and more affordable food system, shifting Ottawa's focus from short-term grocery rebates to the structural causes of high food prices.

The plan includes new investments intended to make grocery retailing more competitive, with money directed specifically at supply chains serving independent grocers — smaller players that have struggled to match the buying power of the handful of large chains that dominate Canadian food retail.

The federal Competition Bureau will also receive increased funding to monitor and enforce competition in food retailing and across supply chains, an extension of the government's running confrontation with grocery concentration since food inflation surged earlier in the decade.

A central strand of the strategy is domestic capacity: ensuring Canadian farmers, processors and shippers are equipped to feed Canadians first. Officials cast the emphasis on food sovereignty as a response to a turbulent global environment, with US tariff policy and armed conflicts — including the war between the US and Iran now disrupting energy markets — straining international food and fertilizer supply chains.

The package also continues work on food insecurity in the North, where previously announced tax incentives for greenhouse construction aim to enable year-round fruit and vegetable production in Arctic and remote communities otherwise dependent on expensive imports.

Thursday's announcement builds on the affordability measures Carney rolled out in January, when the government introduced the Canada Groceries and Essentials Benefit and boosted the GST rebate to cushion households against rising prices. Those programs delivered direct relief; the new plan is pitched at the harder problem of why Canadian food prices rose so far in the first place.

The announcement lands in a difficult economic stretch for the government, which has faced a technical recession, a strained federal budget and provincial friction this year. Food prices remain among the most visible costs for households, making the file as politically significant as any in Ottawa.
