Teacher: Now, understand the problem? Solve this instance: In some prisons, food is a commodity that’s sold, and traded for other items, including contraband 
  
 Two years before the 2016 riot, the Conservative government introduced a national prison menu in an attempt to cut costs. They also established “cook chill” production centres, where food is prepped, cooked, and chilled in a centralized kitchen before being shipped to prisons. These centers, as well as the menu changes, reduced the price of food to $5.41 per day for each inmate, saving the government $6.4 million annually. Powdered milk was substituted for fresh milk, bulky meat portions replaced more select cuts, expensive grains were cut out, vegetable selection was reduced, and English muffins were replaced by toast. These changes led to a rise in inmate grievances, the report said. 
  
 Alan Zinger, in his first report as correctional investigator, the government’s prison watchdog, asked Correctional Services Canada (CSC) to look into allegations of conflicts between prison kitchen employees and inmate workers, and complaints about food shortages, portion sizes, and the daily protein allotment.

 “The immediate triggering events of the Saskatchewan Penitentiary riot appear to be related to unresolved demands regarding inmate dissatisfaction with food… as well as perceived mistreatment of inmate kitchen workers by [Correctional Service of Canada] staff,” said the report released on Tuesday.

 In some prisons, food is sold and traded for other items, including contraband, said the report, which recommended an external evaluation of food services that would address inmate concerns. 
  
 An audit of food services in prisons is currently underway, and it’s expected to be completed next year, according to the Ministry of Public Safety.

 Zinger also noted a number of other issues across the prison system, beyond food, including the lack of therapeutic services for women in Canada’s federal prisons. Conditions in secure units in maximum security jails aren’t appropriate for people struggling with serious mental illness, the report said. Zinger criticized the “entirely inappropriate” practice of temporarily housing mentally ill women in all-male treatment facilities and holding them in isolation. 
  
 The continued use physical restraints, clinical exclusion, and segregation to manage people who are in psychological distress is also problematic, Zinger’s report said. He noted that keeping inmates in observation cells with nothing but a security gown, a security blanket, fluids and food that can only be consumed without cutlery could actually worsen someone’s psychological issues. 
  
 “At (the) Edmonton Institution, I witnessed outdoor segregation ‘yards’ that were actually cages, easily mistaken for a dog run or kennel” 
  
 The amount of time and frequency inmates are spending in solitary confinement has dropped in Canada’s federal jails, according to the report, but some segregation cells still lack appropriate ventilation, windows and natural light, and segregation yards are no better. 
  
 “At (the) Edmonton Institution, I witnessed outdoor segregation ‘yards’ that were actually cages, easily mistaken for a dog run or kennel,” Zinger wrote. “I was told that these so-called ‘yards’ were built at a time when segregation numbers were double what they are today.”

 Zinger said he’d seen many instances of inmates not “participating in any sort of educational, vocational or correctional programming,” that would allow them to find a job when released. He also noticed women mostly working in gendered roles, like textiles, laundry and sewing. 
  
 Corrections officials said they “welcome” Zinger’s report and pledged to follow through on some of its recommendations, like creating a bulletin about the lessons learned from the Saskatchewan riot to be distributed throughout the department. Federal prison official also say they fully support Zinger’s recommendation to provide care for mentally ill women prisoners at local hospitals, although in the interim, prisons will continue to treat women in all-male regional treatment centres in emergency circumstances. ||||| It's scary dairy for one dangerous offender. 
  
 But a Federal Court judge says serving powdered milk in prison isn't actually torture. 
  
 "I find that the provision of powdered milk does not constitute cruel and unusual punishment," Justice Alan Diner wrote in a ruling handed down last week. 
  
 The judge dismissed an application for a judicial review by a prisoner in an Ontario medium-security penitentiary who lost a grievance over a Correctional Service of Canada policy replacing liquid milk with its powdered equivalent.

 According to the ruling, Warkworth Institution began providing inmates with powdered milk in August 2015 as part of a Canada-wide effort to standardize the meals of male prisoners. The prison is located about 50 km west of Belleville, Ont. 
  
 William A. Johnson claimed the move breached his Charter rights, because "he and other inmates were unable to drink powdered milk and were therefore being denied their daily nutritional intake." 
  
 The prisoner claimed that the "majority of society dislikes and/or are unable to drink mixed powdered milk." 
  
 Not 'trivial' to those who consume it 
  
 In response, the attorney general of Canada argued — in part — that the Charter of Rights and Freedoms "does not protect against trivial limitations of rights." 
  
 But the menu in Canadian prisons has proven to be anything but a trivial concern for those consuming it. 
  
 In his annual report to Parliament last year, correctional investigator Ivan Zinger said his office has seen a flood of complaints about portion size, quality and selection of food.

 He traced the issue to a 2014 decision under the previous Conservative government to find ways of lowering "raw food input costs" in order to square a 2,600-calorie daily diet with a cost of $5.41 per inmate per day. 
  
 "Among other measures, powdered milk was substituted for fresh milk, bulky meat portions replaced more select cuts, expensive grains were removed, vegetable selection was reduced and English muffins were replaced with toast," Zinger wrote. 
  
 "Not surprisingly, when these changes were first introduced, inmate grievances related to food issues spiked." 
  
 Dissatisfaction turned deadly in 2016 during a riot involving 200 inmates in Saskatchewan Penitentiary; quality and portion sizes were cited as a "contributing factor" in the confrontation. 
  
 West Coast Prison Justice Society executive director Jennifer Metcalfe says powdered milk is a source of constant frustration for prisoners. 
  
 "It seems sort of insignificant to us in the community, but when every aspect of your life is controlled by Corrections, things like powdered milk take on more importance to people's daily lives," she said. 
  
 "I know a lot of people really struggle with food in prison." 
  
 'Really difficult' to challenge 
  
 The federal court decision notes that the Correctional Services of Canada document detailing Johnson's complaint contained information about his convictions and status as a dangerous offender. 
  
 The ruling doesn't specify what the nature of his crime was. Johnson argued that his offences were irrelevant to his problem with the menu. 
  
 Prison officials told Johnson that if he had an allergy to powdered milk, he could work with a dietitian to come up with a solution, but the ruling said he gave no evidence of "his alleged medical inability to consume powdered milk." 
  
 Ultimately, Diner concluded that Johnson had failed to put forward sufficient facts to make his case for a Charter breach. 
  
 The Correctional Service of Canada says its prison food — including the milk — meets Health Canada's consumption guidelines for men aged 31 to 52. 
  
 Metcalfe says fighting those rules is an uphill battle. 
  
 "I think it would be really difficult for a prisoner to successfully challenge something like that, because they would need to have evidence that contradicts the government's evidence about it meeting the guidelines," she said. 
  
 "But they can't go out and get a second opinion from a doctor. Every aspect of their life is controlled by Corrections, including what medical professionals they can see." 
  
 In addition to losing the case, Johnson was also ordered to pay $250 in costs to the attorney general. |||||

A Canadian inmate has lost his fight over powdered milk. The prisoner filed a grievance over the Correctional Service of Canada's policy of using the powdered dairy product rather than liquid milk, which was enacted in his facility in 2015, arguing that it violated his rights. William Johnson had claimed that he and other inmates cannot drink powdered milk (noting that the "majority of society dislikes and/or are unable to drink mixed powdered milk") and were thus "being denied their daily nutritional intake." Johnson stated that he previously used non-powdered milk in his cereal and was now prevented from consuming cereal as well. But a Federal Court judge last week dismissed Johnson's application for judicial review, finding that serving powdered milk to prisoners "does not constitute cruel and unusual punishment," as Justice Alan Diner wrote in his ruling. He further found Johnson provided no evidence to substantiate his "alleged medical inability to consume powdered milk." The attorney general argued that Canada's Charter of Rights and Freedoms "does not protect against trivial limitations of rights." The CBC notes that since a 2014 government decision having to do with lowering prison food costs, there have been many complaints in Canada about what is served in prison, how much of it is served, and how high in quality it is. A 2015 CBC article noted that the food was being blamed for causing malnourishment, vomiting, and diarrhea. Vice News reports things came to a head in 2016, when a riot at a Saskatchewan prison left one inmate dead; a probe into the incident found "inmate dissatisfaction with food" was a triggering cause.
