#### BENEFITS/PERKS/OTHER

### EMPLOYEE BENEFITS
We have a tax-qualified 401(k) Retirement Savings Plan, or the 401(k) plan. All eligible employees may participate in our 401(k) plan, including our NEOs. Under our 401(k) plan, employees are eligible to defer a portion of their salary, and we currently match a portion of each eligible employee's contributions. We do not enable our employees to invest in our Common Shares through our 401(k) plan.

#### PERQUISITES AND OTHER PERSONAL BENEFITS
We provide no perquisites or other personal benefits to our NEOs, except as disclosed in our Summary Compensation Table in "–Summary Compensation and Other Tables" below.

WHAT INFORMS OUR PAY DESIGNS, METRICS AND DECISIONS

We use our pay designs, metrics, and decisions as some of many tools to:

• attract, retain, motivate and provide direction and parameters to top talent.

• encourage the achievement of our business strategies and operational goals.

• encourage appropriate risk taking and reflect sound corporate governance practices.

• align NEOs’ and shareholders’ interests and support sustainable value creation.

Our CNCG Committee, in consultation with our outside compensation consultant, FPC, conducts compensation benchmarking analyses to ensure that our compensation programs for our NEOs and independent trustees are competitive with those of certain other publicly traded REITs (each, a "Benchmarking Analysis" and together, the "Benchmarking Analyses"). The Benchmarking Analyses include a comprehensive review of each component of the total compensation opportunities for our NEOs and independent trustees relative to market data for REITs with market capitalization, enterprise value, and business model similar to that of our Company. We refer to this group of REITs as our "peer group". The peer group used for the 2023 and 2024 independent trustee Benchmarking Analysis and 2022 NEO Benchmarking Analysis is listed below.
