If i only have quebec coverage, will i be able to use my data in another province?

You cannot use yoru data outside of your coverage area, if you require data in other provinces then you need to adjust your plan to Canada wide coverage and then you can roam for free and use data across Canada.
Otherwise you can add money to your wallet and pay as you go. Since Fizz is prepaid, there is no way to use services you don't have in your plan which is a good thing otherwise you would have incurred overage charges for your data roaming
