"When Harry was in town it wasn't too crazy. There were maybe five paparazzi on the house, but they were discrete," the source notes. "There was additional security on the street, but even that wasn't too intrusive. It was pretty low key. Meghan and Harry never left the home. They just stayed indoors -- and that was before the snowfall."
"It's a quiet street, very residential," a neighbor also tells ET about Meghan's Toronto digs. "It's a safe neighborhood."
Meghan also appears to be pretty low-key when it comes to her everyday life. The avid cook has been spotted walking to nearby Loblaws grocery store -- Meghan memorably carried bags from Whole Foods to Kensington Palace when she visited Harry in London in November -- where she didn't call any attention to her appearance.
"She wasn't wearing makeup or had her hair done, just bundled up like everyone else," a Loblaws employee tells ET about one sighting of Meghan after the news broke of her relationship with Harry. "She walked home."
Aside from grocery shopping, the actress' regular routine includes yoga. Meghan frequently attends classes at a cozy studio in Toronto, which isn't as flashy and modern as other more high-end yoga studios.
"She goes to yoga often and seems to enjoy it," an eyewitness tells ET. "She's always smiling and happy when she leaves."
Still, Meghan isn't just a homebody -- she does enjoy her nights out with friends. Meghan's been photographed at the Four Seasons Hotel in the swankier neighborhood of Yorkville, and has been known to frequent members-only club, Soho House.
An industry source notes that Meghan has friends in high places in Canada.
"She's very gracious and has substance, but she isn't someone who wanted to just fly under the radar," the source says of Meghan. "She's best friends with Jessica Mulroney [the wife Ben Mulroney, the son of former prime minister Brian Mulroney], so she's already sort of aligned herself with Canadian royalty."
Earlier this week, Meghan and Jessica, a fashion stylist, were photographed shopping together in Toronto while bundled up for the snow.
Jessica also Instagrammed a cute pic of Meghan dancing with Jessica's daughter, Isabel, earlier this week. "LADIES NIGHT @meghanmarkle teaching one of her favorite little ladies to tap dance. Quite the weekend fête!" Jessica wrote.
Meanwhile, it appears Harry and Meghan's relationship is only heating up. On Wednesday, the couple was photographed out together for the first time, taking in the Christmas lights and a theater performance in central London.
