CNL employees who choose to work remotely the majority of the time are provided with the equipment required to be successful at their remote workplace (laptop, chair, monitor, etc.); however, they are not provided a dedicated onsite office. CNL’s Chalk River laboratory is nestled in the Ottawa Valley. It affords our employees an area that is environmentally pristine with extensive forests, hills and numerous small lakes, all of which support a variety of wildlife typical to the southern edge of the Canadian Shield. Many surrounding towns, such as Pembroke, Petawawa, and Deep River, provide you with unparalleled outdoor adventures at your doorstep!
