NFPA 652 (2016) states that a dust hazard analysis should be completed for all new facilities. 

For existing facilities, even those that are NOT undergoing material modification, NFPA 652 states that the owner/operator must schedule and complete DHA's of existing processes and facility compartments within a 3-year period from the effective date of the standard. Since the effective date of that standard was Sept.7, 2015, this means that the deadline to conduct the DHA has passed (on Sept.7, 2018).

The new CSA Z432 machine guarding Standard is out and has some interesting improvements. It is only 8 pages longer than the previous version but actually provides more useful information and quantifiable targets. It took effect on October 2016.

The following text is reproduced from http://shop.csa.ca:

Overview
Moving machine parts have the potential to cause severe injuries in the workplace and a significant percentage of injuries in the workplace can be attributed to machine-related incidents each year. Machine safeguarding measures are essential to protecting the workers who come into contact with machines as part of their job duties. Any machine that may cause injury must be safeguarded.
The third edition of CSA Z432- Safeguarding of Machinery specifies requirements for the design, manufacture (including remanufacture and rebuilding), installation, maintenance, operation, and safeguarding of industrial equipment to prevent injuries and accidents and enhance the safety of personnel who operate, assemble, and maintain machinery. The need for a new edition was prompted by the changing technology related to these machines and the wish of stakeholders, including regulators, employers, manufacturers, and labour, for a document that would reflect the latest thinking concerning operator and equipment safety.

CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of federal, provincial, and territorial occupational health and safety government agencies.

Highlights of Z432

• Expanded Scope to incorporate new international Standards on machinery design and performance and to provide additional information for the identification of hazards, including non-mechanical
• Contains the methodology for performing a comprehensive risk assessment
• Applies to newly manufactured, rebuilt, and redeployed machinery but may also be used to set upgrade targets for existing machinery
• Provides advice on the basic principles of safeguarding and safety control performance

On November 23, 2016 the Ministry of Labour provided more information on "How to Apply Section 7 of the Industrial Establishments Regulation"
These web pages provide more information on important questions such as: "How do I get an exemption from Pre-Start Health & Safety Review?" and "Do I need a Pre-Start Health & Safety Review when I move?"

The Ministry of Labour announced a blitz over the period of January 18 – February 26, 2016, focusing on hazards that could lead to serious worker injuries, such as amputations of limbs, or death. The primary focus of the blitz will be machine guarding and lockout.

The following is a flash file from CSST (Quebec)

Beginning April 1, 2015, employers in Ontario must ensure that workers on construction projects who may use certain methods of fall protection successfully complete 'working at heights' training that meets training program and provider standards established by the Chief Prevention Officer (CPO).

The Occupational Health and Safety Awareness and Training Regulation (Ontario Regulation 297/13) under the Occupational Health and Safety Act (OHSA), has been amended to include mandatory working at heights training requirements. The working at heights training is valid for three years from the date the worker completes an approved training program delivered by an approved training provider.
