Hi you could say: The opinions of a few cannot represent the views of the whole group.

Hello. here is a correct sentence: I was able to prevent a bad review from my employer on my profile by removing his project. I suppose it is better now, at least he is not able to write a bad review on my profile.

Hi, yes its correct to use come when you are inviting them while you are already in the country. You have made a few mistakes, I have fixed them below :) I am in Turkey at the moment but sometimes I go to Toronto and stay there for a long time.

I want to ask them why they have not come to Toronto? or when are you coming to Toronto? - you can ask them either question above.

A trip do Luís Correia

Hi there! Today I'd like to talk about a trip that I did last month. I took my family to Luís Correia, a city on the coast. It's a city 350 km away from mine. I don't like to drive fast, especially when I'm with my family. So it took about 5 hours to get there. We rented a good house, which was located 400m from the beach. It couldn't be better located.
In order to save some money, we decided that, instead of having meals at restaurants, we would buy food and prepare meals at home. Therefore, we bought shrimps, fish, and meat to eat. Man, it was soooo good!
So our daily routine was pretty much the same, every day. We woke up early, like... 6 am, we prepared the breakfast, got dressed and then we went to the beach.
On one of the days we went to 3 different beaches and, in one day, we went to the mall. After going to the mall we went to eat a pizza. but, to be honest, the pizza was not tasteful.  The pizza, to be honest, was not tasty. 
After 6 days, we went back home. Just after the city, there was a farm where we bought cheese and sweets.
That's it for now. Thanks for correcting me. You guys take care!
