In my opinion to be truthful, it will be cost prohibitive for you to bring out any type of drillrig to your site unless you are very lucky and one is working "next door" and will not charge you any mobilization. Hopefully you bought a good site - see comments below.
When I was working out of Toronto some 17 years ago - the cost of an investigation went something like:
Mob/demob of drill: Then about $60/hr or some charged by km.
Drilling - hourly basis - then over $100/hr
Expendables - not too bad
Sometimes backhoes may be enough - likely a local small contractor who would charge you by hour to and from his place.
Engr - mob and demob: km for car and pay by hour for time.
Work: hourly basis - likely $75/hr now.
Report - say $500, if simple
Lab testing: if on shoestring - say $150 assuming very straight forward conditions.
Septic field - percolation tests - take time - I have no idea but long ago, they might cost $200 or so as extension of time on site.
You might be better off, at a start, to discuss with the local building inspector - he would know what areas have "poor" house building sites and what areas are of little concern. Sometimes you might get lucky and find previous data from nearby.
If you land is hilly, that creates some problems; if in lowlands - other problems. This is where knowledge ahead of any involvement by a geotechnical engineer may prove valuable.
If you know of a backhoe around, dig a few test pits outside the planned area of your house. See if rock is close. See if soils are "soft" or "hard". Do you have a lot of water coming into the test pit? Having this information, then contact a geotechnical engineer; give him the information you have - be truthful. If you have collected samples of the materials encountered, so much the better. I know some Toronto area geotechs who have cottages up there and if you find one who is visiting, you might be able to get him to do a quick check for next to nothing - of course, he has to protect himself and his firm - and I believe, now, he will have some forms to fill out for the building permits.
The bottom line, costs may be relatively small if you have a good site - costs will go up especially for investigation if you have a crummy site.
