"What a amazing feeling here in the stadium!!! Let's go canada!!" tweeted diver Roseline Filion after she followed flag-bearer Simon Whitfield into Olympic Stadium.
Whitfield held the Maple Leaf high as he led in a Canadian contingent wearing red-and-white jackets, khaki pants and white sneakers.
"Can't watch the whole thing, but I'm predicting #TeamCanada best dressed...aside from #JosatekiNaulu from Fiji of course," tweeted women's soccer player Melissa Tancredi, who along with her teammates missed the opening ceremony to rest up for their match Saturday against South Africa.
Several Canadian athletes, including some of Filion's diving teammates, did not take part in the festivities to focus on their events. They still took time to post what they thought of the proceedings.
"THAT IS WHY CANADA IS SO BEAUTIFULL!! FEEL THE LOOOVVEE!!!," diver Alexandre Despatie tweeted as the Canadian tem entered Olympic Stadium. "Everyone at home should feel a part of this!!"
Even athletes not taking part in the Olympics seemed impressed by the pagentry.
"If you're not watching the opening ceremonies you don't like sports!" tweeted hurdler Priscilla Lopes-Schliep, who won a bronze medal at the 2008 Beijing Games but failed to qualify for London.
"Feeling nostalgic while watching the opening ceremony in London! Feels like Vancouver was yesterday!" added figure skater Joannie Rochette, who won a bronze medal at the 2010 Vancouver Games.
Before the athletes came out, the ceremony featured a show that touched on key eras of British history before breaking into a celebration of the country's contributions to pop music.
"I suddenly regret falling asleep in history class," posted former world champion hurdler Perdita Felicien during a lengthy Olympic-style recreation of the Industrial Revolution.
Not everyone watching was impressed, however.
"The Rona Commercial was my favorite part of the opening ceremonies so far," tweeted speedskater Denny Morrison.
