WiF0215 - Waterloo is near the Toronto metroploitain area so you will have no trouble finding and locating members from your home country if that suits your fancy. Toronto has some famous tall tower there which I think they let you go up to a certain level to see the scenary from above.
Actually a little history - Waterloo sits on a swamp - drained of course and the first settler to arrive was a Mennonite from Pensylvania who I guess bought a few acres of swamp land. Not to be deterred though with his new purchase he drained the swamp, built a log camp, grist mill, school, and formed a community which later became known as Waterloo. I think the individuals name was Ezra and of course he did not do it all by himself but his name predominates. There are some surviving relics of that time around the early 1800's that you could check out.
You are not too far from Niagara Falls on the US-Canada border- an hour and a half.
And not too far from the nations capital of Ottawa - about 4 hours.
Another 2 to 3 hours from Ottawa and you could be in Montreal, Qc where you could experience some french culture which by the way is no different than any other culture in N. America, except for the french thing, and most understand english anyways considering that the province of quebec was 75% english speaking at one in the past anyways.
Since you are here only for the summer you will have missed the sugaring off season which is just an excuse to go to a "big house converted to a restaurant" in a country setting and eat a lot and then eat more. They still offer that during the whole summer and winter but then you just can't say you then went to a sugaring off festival. Sugaring off is collecting the sap from maple trees, boiling it in a big tub and making maple syrup. You might want to take some of that back with you as gifts back home.
You can go see lake Huron, Lake Erie and Lake Ontario and maybe do some fishing, waterskiing or other fun stuff in cold water. I do not know if you can eat the fish with three eyeballs though.
You can extend yourelf further west to see Lake Superior and lake Michigan which are the last 2 of the 5 Great Lakes which I think are the largest fresh water lakes in the world. By fresh it is meant that it is not salty, and not necessarily fresh to drink because fish do poop and pee.
You will find restaurants Italian, Greek, Vietnamese, Indian, japanese, Polish, Chinese etcetera for what suits your fancy in most metropolitan areas if you do not like Canadian food which is meat vegetables and potatoes with desert and coffee - an all around well balanced diet. and don't forget bread and buns.
Tea is not as well established a drink. But you will find that if you investigate enough you will find a certain store in that will sell what you are used to in drinks and food so you do not get so homesick.
By the way you can't see it all in one summer.
I hope to see the Niagara falls at least. Let's see how much free time my adviser leaves me.
