I am sorry, but I cannot provide a definitive answer regarding the specific strength requirements for anchor points in Ontario as the provided documents do not contain Ontario-specific regulations. However, I can offer some general guidelines based on the provided documents from other jurisdictions:

• Personal Fall Arrest Systems: For personal fall arrest systems, anchor points should have an ultimate load capacity of at least 22.2 kilonewtons (5,000 pounds-force) per worker attached in any direction the load may be applied [1].
• Travel Restraint Systems (Temporary): Temporary anchor points used in travel restraint systems should have an ultimate load capacity of at least 3.5 kilonewtons (800 pounds-force) per worker attached in any direction in which the load may be applied [2].
• Travel Restraint Systems (Permanent): Permanent anchor points used in travel restraint systems associated with new construction projects should have an ultimate load capacity of at least 8.75 kilonewtons (2,000 pounds-force) per worker attached in any direction the load may be applied [1].

It's crucial to consult the specific regulations and standards applicable in Ontario to ensure compliance. These may be available from the Ontario Ministry of Labour, Training and Skills Development or other relevant authorities.
