There’s heaps going on in the capital this weekend, including the launch of a brand new venue , which will open with a bang in a literal sense, and the Wimbledon tennis championships, if you’re prepared to wait in line.

Canada Day

It’s time to celebrate Canada, and how better than with a ceremonial Drop of the Puck by the Canadian High Commissioner before eight teams compete in a street hockey tournament to kick off Canada Day in Trafalgar Square? You can also meet the Mounties and gorge on a pancake breakfast at the party, which is the largest celebration of Canada Day outside the country itself. 1 Jul

Wimbledon Lawn Tennis Championships

If you’re committed to your tennis, tickets to Wimbledon can be bought on the day at the ground at the All England Club. Each day around 500 tickets are available on a first-come, first-served basis for courts 1, 2 and Centre Court (except on the final four days for Centre Court). Several thousand tickets for courts 3 to 19 are also on sale – they also allow access to Murray Mount (formerly Henman Hill) where you can watch the top players on Centre Court on a big screen. Be prepared to queue from 8am for ground passes or overnight to guarantee show court tickets. Until 8 July

London Festival of Architecture

‘The Playful City’ is the theme for this year’s festival of London architecture and the Fitzrovia Hub is the focus this weekend. Architecture practices in the area – including London’s architectural HQ at RIBA in Portland Place – are opening their doors for workshops, open studios, exhibitions and games. You can download a Fitzrovia Trail map to guide you over the weekend. 30 Jun-1 Jul

London Pleasure Gardens launch

Don’t miss the chance to explore East London’s brand new cultural hub. London Pleasure Gardens has been built on a derelict dock and will open its doors on Saturday for the first time. Its launch event is the free Paradise Gardens Festival, which promises a spectacular fire and pyrotechnic show from The World Famous firework company. It will fuse music, pyrotechnics, projection and theatre. 30 Jun-1 Jul

As our World in London series continues, we come to our friends in Canada. Writer and comedian Ryan Millar tells us the best place for Canadians to get their caffeine and sugar fix in London:

When I first rode by 56 Haymarket, SW1, I did a double-take. Across four busy lanes of traffic I glimpsed a frosted Tim Hortons logo. I couldn’t resist stopping. There are more than 50 Tim Hortons in London, Ontario, but I wasn’t expecting any in London, England? I had to get a taste.

Doughnuts and coffee have a peculiar magnetism on the Canuck. Almost any journey made by a Canadian – be it a quick pick-up from hockey practice, a family road trip to Head-Smashed-in-Buffalo-Jump, or – evidently – a cycle through central London to the Royal Academy of Arts, can be waylaid by Tim’s coffee and doughnuts.

The coffee is earthy and spicy with notes of nostalgia. And the panoply of baked goods is a feast of fruit and sugary deliciousness, perfectly formed to feed a nation. How else to explain that Tim Hortons is, by some accounts, a bigger fast-food retailer in Canada than McDonalds, and a bigger coffee chain than Starbucks?

And it’s now available right in the centre of the swirling metropolis of London, England – just a two minute walk from Leicester Square and half that to Piccadilly Circus. For any Canadian feeling far from home, the comfort of comfort food can be sweet in both the “double sugar” and metaphorical senses.

However, the Haymarket Tim Hortons isn’t a full-blown outlet. No such luck. It is just a small wall display in the Spar supermarket. The doughnut selection isn’t huge (What? No crullers?) and the coffee comes from a self-serve machine on the counter.

But there’s no mistaking it – this is a Tim Hortons coffee and doughnut. And that’s enough for me.
