£30000 salaray + 4% pension in Glasgow, UK. what will be same salary in toronto, canada?

A 30K quid gross salary is about CAD$47,000 here. If that was your before-taxes salary, you would likely have a net pay of around CAD$35,000 when you take off the Ontario income tax, employment insurance, Canada pension plan contribution, and any other fees or taxes that may be on your paycheque. And Toronto is one of the most expensive cities in Canada to live in. Apartment rentals are routinely over $1000 per month, your monthly public transit pass would cost about $125, and you'll have to pay for phone ($20), internet ($30), cable TV $(30) separately, as those are not usually included in an apartment rental. And of course there is food. Expect anywhere from $50 per week if you eat only cheap cuts of meat and buy everything on sale, to about $200 per week if you tend to eat out at restaurants a lot. Sales tax on what you buy at a store or restaurant is called HST and is around 13% (like the VAT in UK). Adding all those weekly and monthly costs up, you have about $25,000 worth of expenses, and that's not including any furniture, clothing, home insurance, or unexpected expenses that may come up. The $47,000 is a little more than double the Ontario minimum wage. You can live on that, but you may want to consider living in a less expensive part of the city, or hopefully find a job that pays better.

It depends what you do to earn the 30K. Some jobs there have no demand here while others may pay a lot more here. Without knowing your profession this cannot be effectively answered.
