First, get to know as much as you can about Canada, its Provinces and Territories. Like you asked, you will get a pretty good overview of its culture, food, festivals, history, climate, geography, economy, demography, governments (federal/provincial/municipal).

Secondly, get know the many generations of Ukrainian Canadians that live here throughout Canada. You may find long lost relatives or even old friends 😁 and then Canada won't be much different from Ukraine, just more people of various culture, religion and walks of life, everyone chipping in trying to make a positive difference in each others lives (although Canada has it own assholes and criminals, they generally tend to not openly/bombastically flout the law).

Work wise, I would recommend to focus on anything related to sustainable development, climate change adaptation and the tech sector as those are where all the investment are being thrown into (renewable energy sector, electric transportation and manufacturing chain, mineral resources exploitation, forestry and sustainable agribusinesses, etc.)

Hopefully, my Canadian 2 cents helps. 😆
