  • Ontario Firefighters' Wages in Neoliberal Times
    Braedley 129 A LADDER UP: ONTARIO FIREFIGHTERS’ WAGES IN NEOLIBERAL TIMES Susan Braedley Postdoctoral Fellow, CHSRF/CIHR Chair in Health Services Research, York University, Toronto, Ontario, Canada INTRODUCTION They deserve it. You can’t put a price on people that are in a profession of saving people’s lives…You cannot compare people who save lives to people who pick up garbage or cut grass. If they [the other unions] try to use that comparison, we will blow them out of the water. (Toronto City Councillor Rob Ford, quoted in Gray 2007, commenting on firefighters' wage increase). he seismic economic shifts that came to the surface in 2008, dumping thousands of workers out of private sector work. They Tare beginning to hit public sector workers, who are experiencing pressure to make concessions and apprehension that they will be next for lay- offs. Although some governments have shown willingness to accumulate debt in these times, public sector workers are bracing themselves for an expected round of re-structuring, justified by declining government revenues. As this economic crisis closes the curtain on rampant neoliberalism and opens on what, at first glance, looks like a “revisionist” neoliberal next act, it is worth considering how one public sector unionized occupation – professional firefighting 1 - has been able to adapt to neoliberalism better than other public sector occupations. How and why have firefighters been able to maintain and even strengthen their labour position during a neoliberal period characterized by attacks on public sector wages and working conditions? This paper contributes to discussions about labour inequities by investigating the relations that have supported this masculinized labour sectors’ position.

  • City of Toronto Emergency Services Is in Agreement with the Introductory Statements and Observations
    Frank Pappone Division Chief William A. Stewart Emergency Services Tel: 416 338-9401 Fire Chief Head Quarters Fax: 416 338-9404 4330 Dufferin St. William Blair Toronto ON M3H 5R9 Police Chief Bruce Farr Emergency Medical Services Chief April 4, 2008 Director General, Spectrum Engineering Branch, Industry Canada, 1943B, 300 Slater Street, Ottawa, Ontario, K1A 0C8. Canada Gazette Notice SMSE-004, Proposed Revisions to the Frequency Plan for Public Safety in the Band 700 MHz. The City of Toronto’s Emergency Services welcomes the opportunity to provide comment on Canada Gazette Notice SMSE-004, Proposed Revisions to the Frequency Plan for Public Safety in the Band 700 MHz. Since 2000 the City of Toronto has operated a common voice radio system infrastructure utilizing approximately 7000 terminals for its Emergency Services agencies. Collectively, Toronto Police Services, Toronto Fire Services and Toronto Emergency Medical Services form one of the country’s largest Public Safety groups representing over 10,000 first responders. Because of this common interest and the impact of the proposed revisions to the frequency plan we felt it best to provide comment as a single unified voice. The comments contained herein represent the consensus of the three agencies. The decision by the FCC in the United States, in August 2007, to amend the 700 MHz band plan to accommodate broadband services in that band has caused a great deal of concern and uncertainty for Toronto’s public safety agencies. Toronto is currently planning a radio system replacement with every intention of operating in the 700 Mhz band. It is imperative that revisions to this plan be finalized and implemented in the most expedient manner possible that recognizes and prioritizes the needs of the public safety community above other interest groups.

  • 595 an Empirical Study of Terrorism Prosecutions in Canada
    EMPIRICAL STUDY OF TERRORISM PROSECUTIONS IN CANADA 595 AN EMPIRICAL STUDY OF TERRORISM PROSECUTIONS IN CANADA: ELUCIDATING THE ELEMENTS OF THE OFFENCES MICHAEL NESBITT* AND DANA HAGG** It has now been over 15 years since Canada enacted the Anti-Terrorism Act, codifying what we think of today as Canada’s anti-terrorism criminal laws. The authors set out to canvass how these provisions have been judicially interpreted since their inception through an empirical analysis of court decisions. After exploring how courts have settled initial concerns about these provisions with respect to religious and expressive freedoms, the authors suggest that courts’ interpretations of Canada’s terrorism offences still leave us with many questions, particularly with respect to the facilitation and financing offences. The authors explore these questions and speculate about future challenges that may or may not be successful with the hopes of providing guidance to prosecutors and defence lawyers working in this area.

  • What Does Energy Security Mean for Canada?
    Canadian Energy Security What Does Energy Security Mean for Canada? 2009-10 Capstone seminar student report Graduate School of Public and International Affairs, University of Ottawa In collaboration with the Canadian Security Intelligence Service Canadian Energy Security Page | 2 This report highlights the results of a Capstone seminar on Canada and Global Energy Security given (in English) by the University of Ottawa in 2009-10. The Capstone seminars expose graduate students to strategic issues and are jointly designed and taught by a member of faculty and a practitioner. The seminar covered by this report results from close collaboration between the university and Canada’s security and intelligence community. Guided by the seminar supervisors, its content was developed by the participating students and does not represent formal positions on the part of the organizations involved. The report is not an analytical document; its aim is to support future discussion.

Securing the processes through which that energy is produced, delivered and consumed is therefore of paramount importance. Many countries view the primary goal of energy security to be securing a reliable supply. In the case of Canada, a country rich in energy resources, energy security is a more complex concept.

Heavy snow fall and freeze-thaw events can damage property and infrastructure, cause power outages and creates hazardous driving conditions. In many parts of the province the winter season is becoming less predictable with more frequent temperature fl uctuations. These changes in climate and weather patterns are expected to continue and become more severe. Changes in winter conditions may impact recreational and economic activities as well as public health and safety. Melting snow replenishes surface and ground water sources, so less snow cover may reduce the amount of water available during the rest of the year; impacting the agricultural sector as well as the public water supply. As with all severe and hazardous weather, it is important to know what to expect and how to prepare. Also, understanding how winter conditions may change can help you prepare for the associated risks and may help minimize impacts. *Please note that avalanches are covered in the Slope Movement Chapter of this workbook. e Town of Bonavista, NL, a er a snow storm.
