Temporary Equity [Abstract]
Preferred Stock [Text Block]	12. Preferred Stock Series B-1 Preferred Stock On April 15, 2020, the Company and SunOpta Foods entered into a subscription agreement (the "Series B Subscription Agreement") with Oaktree Organics, L.P. and Oaktree Huntington Investment Fund II, L.P. (collectively, "Oaktree") and Engaged Capital, LLC, Engaged Capital Flagship Master Fund, LP and Engaged Capital Co-Invest IV-A, LP (collectively, "Engaged Capital"). On April 24, 2020, pursuant to the Series B Subscription Agreement, SunOpta Foods issued 15,000 shares of Series B-1 Preferred Stock to each of Oaktree and Engaged Capital for aggregate consideration of $30.0 million and 30,000 shares total (the "Series B-1 Preferred Stock"). In connection with the issuance of the Series B-1 Preferred Stock, the Company incurred direct and incremental expenses of $4.0 million, which reduced the carrying value of the Series B-1 Preferred Stock. The carrying value of the Series B-1 Preferred Stock is being accreted through charges to accumulated deficit over the period preceding April 24, 2025. For the year ended December 31, 2022, these accretion charges amounted to $0.7 million (January 1, 2022 - $0.5 million; January 2, 2021 - $0.3 million). The Series B-1 Preferred Stock had an initial stated value and liquidation preference of $1,000 per share, which is adjusted for any non-cash dividends declared on the Series B-1 Preferred Stock (the "Series B-1 Liquidation Preference"). Cumulative preferred dividends accrue daily on the Series B-1 Preferred Stock at an annualized rate of 8.0% of the Series B-1 Liquidation Preference prior to September 30, 2029, and 10.0% of the liquidation preference thereafter (subject to an increase of 1.0% per quarter, up to a maximum rate of 5.0% per quarter on the occurrence of certain events of non-compliance). Prior to September 30, 2029, SunOpta Foods may pay dividends in cash or elect, in lieu of paying cash, to add the amount that would have been paid to the Series B-1 Liquidation Preference. The failure to pay dividends in cash for any quarter ending after September 30, 2029 will be an event of non-compliance. For the second quarter of 2020, SunOpta Foods elected to declare dividends on the Series B-1 Preferred Stock to be paid in kind and, as a result, the aggregate Series B-1 Liquidation Preference increased by $0.4 million to $30.4 million, or approximately $1,015 per share. Since the second quarter of 2020, SunOpta Foods has elected to pay the quarterly dividend amount of $0.6 million in cash. As at December 31, 2022, the Company accrued unpaid dividends of $0.6 million for the fourth quarter of 2022, which are recorded in accounts payable and accrued liabilities on the consolidated balance sheet. At any time, the Series B-1 Preferred Stock may be exchanged, in whole or in part, into the number of Common Shares equal to, per share of Series B-1 Preferred Stock, the quotient of the Series B Liquidation Preference divided by $2.50 (such price, the "Series B-1 Exchange Price" and such quotient, the "Series B-1 Exchange Rate"). As at December 31, 2022, the aggregate shares of Series B-1 Preferred Stock outstanding were exchangeable into approximately 12,178,667 shares of common stock of the Company ("Common Shares"). The Series B-1 Exchange Price is subject to certain anti-dilution adjustments, including a weighted-average adjustment for issuances of Common Shares below the Series B-1 Exchange Price, provided that the Series B-1 Exchange Price may not be lower than $2.00 (subject to adjustment in certain circumstances). SunOpta Foods may cause the holders of the Series B-1 Preferred Stock to exchange all of their shares of Series B-1 Preferred Stock into a number of Common Shares equal to the number of shares of Series B-1 Preferred Stock outstanding multiplied by the Series B-1 Exchange Rate if (i) fewer than 10% of the shares of Series B-1 Preferred Stock issued on April 24, 2020 remain outstanding, or (ii) on or after April 24, 2023, the volume-weighted average price of the Common Shares during the then preceding 20 trading day period is greater than 200% of the Series B-1 Exchange Price then in effect. At any time, if a holder of Series B-1 Preferred Stock elects to exchange, or SunOpta Foods causes an exchange of Series B Preferred Stock, the number of Common Shares delivered to each applicable holder may not cause such holder's beneficial ownership to exceed 19.99% of the Common Shares that would be outstanding immediately following such exchange (the "Series B-1 Exchange Cap"). At any time on or after April 24, 2025, SunOpta Foods may redeem all of the Series B-1 Preferred Stock for an amount per share equal to the value of the Series B-1 Liquidation Preference at such time, plus accrued and unpaid dividends. Oaktree and Engaged Capital are entitled to vote the Series B-1 Preferred Stock with the Common Shares on an as-exchanged basis, subject to a permanent 19.99% voting cap. As a result of the voting cap, each of Oaktree and Engaged Capital will only be able to vote its Series B-1 Preferred Stock to the extent that, when taken together with any other voting securities each investor controls, such votes do not exceed 19.99% of the votes eligible to be cast by all security holders of the Company. On April 24, 2020, the Company designated Special Shares, Series 2 to serve as the mechanism for attaching exchanged voting rights to the Series B-1 Preferred Stock. The Special Shares, Series 2 entitle the holder thereof to one vote per Special Share, Series 2 on all matters submitted to a vote of the holders of Common Shares, voting together as a single class, subject to certain exceptions. The Special Shares, Series 2 are not transferrable and the voting rights associated with the Special Shares, Series 2 will terminate upon the transfer of the shares of Series B-1 Preferred Stock to a third party, other than an affiliate of Oaktree or Engaged Capital, as applicable. As at December 31, 2022, 6,089,333 Special Shares, Series 2 were issued to Engaged Capital, equal to the number of Common Shares issuable to Engaged Capital on the exchange of all of the shares of Series B-1 Preferred Stock held by it, and no Special Shares, Series 2 were issued to Oaktree, as Oaktree was subject to the Series B-1 Exchange Cap. On February 28, 2023, the Company received written notice from Engaged Capital that they have exercised their right to exchange their entire holding of 15,000 shares of Series B-1 Preferred Stock into Common Shares (see note 22). Series A Preferred Stock On October 7, 2016, SunOpta Foods issued an aggregate of 85,000 shares of Series A Preferred Stock to Oaktree for consideration in the amount of $85.0 million (the "Series A Preferred Stock"). On February 22, 2021, Oaktree exchanged all of their shares of Series A Preferred Stock for 12,633,427 Common Shares at an exchange price of $7.00. Upon the exchange, the Company derecognized the $87.5 million carrying amount of the Series A Preferred Stock, including dividends paid in kind, and recognized a corresponding amount for the Common Shares issued on exchange, net of share issuance costs of $0.3 million.
