Margaret Atwood’s Forties childhood was spent knocking around the Canadian backwoods with her forest entomologist, proto-ecologist dad, and it shows. Interviewed alongside her husband Graeme Gibson on the Brighton Festival’s closing night, the international literary prizes, like the gushing reverence with which she’s introduced by Festival director Ali Smith and received by the sell-out crowd, seems to have made little impression. This is a modest, earthy, dryly witty and straight-talking couple, with the self-sufficient air of those familiar with isolated, country living.

“Loving people doesn’t save them” could be the epitaph to the young Canadian director Xavier Dolan’s exuberant, emotionally draining fifth feature Mommy. Its vivid colours, concentrated in an unusual square screen ratio, seem to burst out with devilish energy as we follow the attempts of a loving but stretched mother to look after her 15-year-old son who suffers from attention deficit hyperactivity disorder.

The big news was that dashing Greg Wise was returning to the London stage after an absence of 17 years. Still best remembered as the handsome cad Willoughby in the film of Sense and Sensibility – now 20 years old – he appears in the intimate Park 200 auditorium as a middle-aged, care-worn father, oblivious to wrinkles and grizzled locks. He gives a performance so physically and emotionally charged, however, that his looks are irrelevant.

Jake Gyllenhaal and Canadian director Denis Villeneuve shot Enemy before their collaboration on Prisoners (released in 2013), but already the combination was working stunningly well. In outline, Enemy doesn't sound hugely original – university lecturer Adam (Gyllenhaal) becomes fixated with his own double, an actor called Anthony Claire (also Gyllenhaal), who he happens to spot while watching a movie on DVD, and their lives become progressively entangled after Adam feels compelled to track down his doppelganger.

It’s not obvious, listening to her work, just how funny Tanya Tagaq is. Her modified version of Inuit throat-singing-for-one, introduced to a wider audience on Bjork’s Medulla, has been called many things: intense, powerful, primal.

Timber! would be best described as a folk-themed lumberjack circus show. Its creators, Cirque Alfonse, hail from rural Quebec, but often, as they indulge in jigs and reels, banjo and mandolin, amongst acrobatics and action, their antics recall the more familiar backwoods traditions of the Appalachians, their hillbilly US counterparts. However, the afternoon matinee where I caught the show was filled with families, lots of kids coming to the end of their Christmas break.

Leonard Cohen, grand rabbi of poetry and the blues, turned 80 this year, and like a perfectly matured brandy, he only gets better and better. On his most recent European tour, he managed to combine an atmosphere of deep and communal spiritual devotion with consummate entertainment. Many artists cannot always make the leap between live magic and studio precision, but he has succeeded with a new album that shines in a way no other did for me in 2014.

Walking into this exhibition is a bit like walking into a great forest. The dark green walls are hung all around with paintings of trees; we look up through branches that spiral dizzyingly skyward, while the upwards sweep of vast trunks seem relentlessly, tangibly full of life. Some of these paintings verge on abstraction, the forms of tree trunks simplified and reduced to an arrangement of planes, with spatial recession represented entirely through colour.

This concert was part of a tour of Canada’s National Arts Centre orchestra to five cities in the UK themed around the anniversary of the start of World War One. The Ottawa-based orchestra joined forces with the Royal Philharmonic Orchestra and the London Philharmonic Choir for this London centrepiece to the tour, under the baton of violinist-turned-conductor Pinchas Zukerman.
