"All I have is hope at this point that he will walk in the door and everything will go back to normal," Fewson said.

Fewson said their families were so close, they met up on the Galápagos Islands in January when they were on vacation and stayed on a boat together for a little while.

"Our families get along exceptionally," Fewson said.

On July 1, Fewson, his wife, and a small circle of 40 to 50 people who are friends and family of Campbell held a vigil at Lloyd Robertson Park, near 9th Line and 16th Avenue, wishing and praying for Campbell's safe return home.

They also walked through woods, rivers, and many areas of Markham along Major Mackenzie Drive, going as far as Hwy. 404, posting missing person posters of Campbell, who Fewson describes as a comedian with a wonderful sense of humour.

One time, Campbell called him during the 2016 United States election, pretending to be reporter. Fewson said he and his wife are very politically involved and actually believed it, before Campbell broke out of character after 30 seconds.

"He got me good," Fewson said with a chuckle, remembering the moment.

Campbell is very reliable, Fewson said.

"He’s the guy in the neighbourhood, if I had a heavy fridge that needed to be moved, I would call him.

Campbell has been missing a little longer than a week, and Fewson just wants him to know "he is loved by his community, friends, and family, and we miss him dearly."

Campbell’s sister and sister-in-law created a GoFundMe page for Campbell's family July 2 that has since raised $11,290.

"Both Nathaniel and his wife Casandra are self-employed and not salaried. Given the current situation, unfortunately, there is no ongoing employment income coming in," the page reads.

"At this time, financial support would be extremely helpful and welcomed."

Campbell's wife is completely devastated," Fewson said.

"I am shocked," he said. "This is entirely inconsistent with the wonderful father of three I know."

Campbell is described as white, five-feet, 10-inches tall, weighing 230 lb, with a stocky build. He is balding at the back of his head and has black hair and brown eyes. He has a brown mole under his left eye, and was last seen wearing grey jeans, a backpack and a baseball cap.
