Hi Kabayan!
Which part of Canada are you planning to settle??? Here in Toronto is quite expensive. Although, your job qualifications are quite good but, it is just pure luck if you can find your job easily. I have some friends that are already here and they have to go back to school to upgrade themselves. I am not trying to discourage you but, ... you can be lucky!

The school education here is free. You don't have to pay any single cent even the Catholic schools. But, if you would like your children to go to a private school, I believe it is about $5,000-$1,0000 annually??? I am not so sure the exact figures. That is just for primary.

In terms of expenses, the housing rental is about $1,200 depending on how many bedrooms and how big the house, you are looking for. It is almost the same if you rent the apartment except that you don't have to pay for the utilities like when you in a house.
The Water is about $150.00 every 3 months depending on how much you use.
The Hydro is about $200/month and it goes up during winter months because you have to use a lot of heat most especially when it is about -30 degrees celcius outside.
Food/groceries are quite cheaper here compared to the Phils. Like the 10lbs. rice is about $10.00 and chicken is about $1.29/lbs. Vegetables and fruits are much cheaper.

The basic internet connection like high speed starts from $20/month and telephone is $30/month without long distance to the Phils!

I'm not sure whether is the life insurance you are talking about! But, it depending on how much you want on your coverage. You can get $50/mo. and up. Try to check some websites.

Also,you have to remember, that after 3 months that you arrived here in Canada you will get the full medical coverage. We call it OHIP in Ontario (Ontario Health & Insurance Plan). We pay higher taxes here that is why we don't pay when we go to see the doctor or even to be admitted in the hospital. Everything is covered by the government.
Your children will get some child benefits too depending on your salary.
Here in Ontario, we pay 13% tax on almost anything. The cost of living here in Toronto is quite high. Some provinces are different!

Try to consider some options!

Good luck to you and your family!!
