Diary of the week: Operanation, Butterfly Ball, Wonderful Women and more

The Canadian Opera Company hits a high note each year with Operanation, the company's annual fundraiser, this year themed "Queen of the Night." With an imperative to wear leather, lace and latex, guests turned out in moody ensembles, including Dragonette singer Martina Sorbara, who had the crowd on their feet as she belted out the band's hits while festooned in black lace and feathers. One of the evening's highlights came when rising star soprano Ambur Braid joined the band for a rock opera mashup that left revelers in awe before the crowd filed into the rehearsal space at the Four Seasons Centre to partake in live band karaoke, hosted by drag queens Judy Virago, Tynomi Banks and Allysin Chaynes. Rounding out the fun were a meatball bar, delectable Chocolates X Brandon Olsen, installations by Gillian G, Queen of the Night-themed temporary tattoos by Canadian artists and custom colouring books. We'll sing to that!

A very fashionable group of Torontonians spread their wings (and opened their wallets!) at the 19th annual Butterfly Ball, where an unprecedented $460,000 was raised for Boost Child & Youth Advocacy Centre, the only outlet of its kind in the city. The supremely stylish event saw Suzanne Rogers, Sylvia Mantella, Jenna Bitove, host Cheryl Hickey and more dressed to impress in the latest designer wares at the Four Seasons hotel. Singers Sean Jones and Ivana Santilli, plus saxophonist Miles Raine, kept more than 400 guests entertained as dinner turned into a lively auction, during which a trip to London Fashion Week and a day with Toronto's Emergency Task Force were doled out to the highest bidders.

For its third year, Weizmann Canada's Women and Science committee corralled 300 lovely ladies eager to find ways to help further the fairer sex at the Wonderful Women event. Splash catering provided the food to fuel a passionate panel discussion between award-winning author and musician Jann Arden, businesswoman Carrie Kirkman, actress and author Mary Jo Eustace and Weizmann immunologist Dr. Yifat Merbl. Funds from the gorgeous Casa Loma affair benefit a trio of awards aimed at helping bright female scientists pursue post-doctoral degrees abroad.

Cumberland Street has a new watering hole, and the opening of Bar Reyna brought out a who's who of recognizable names (think Michael Budman, Deepak Chopra and Catherine Nugent) to sample sea bass ceviche, lamp pide and some of the many styles of fries on the bar's coveted list, all washed down with champagne and one of two signature cocktails. With Reyna meaning "queen," guests were coronated with deep purple bracelets featuring gold crowns on arrival - and treated to an aerial performance worthy of a royal court. And over at the Hudson's Bay's flagship downtown, HUGO BOSS rounded up a stylish set that included Glen Baxter, George Antonopoulos and Mary Symons to open their new 1800-square-foot Man and Woman shops within the department store. Guests nibbled on mini glazed short ribs with buttermilk biscuits while enjoying a trends presentation ('90s for men, minimalist for women).
