A suggestion from a friend that knows a lot of folks and makes his living dealing with repair shops is:

M B Auto Repair
Phone: (306) 757-9934
Address
1311 Winnipeg St
Regina, Saskatchewan, S4R1K2

Owner is Mark Bennet.

MB auto is where i have gone for years Mark knows his stuff. and they are honest nice people.

Take it to the local Canadian tire and get the pan dropped and the seal replaced. Pretty easy job with a hoist.

Update:

Mark at MB was not able to do the work for at least two weeks. He recommended Rod over at Zaran's Cylinder Head repair. I spoke to Rod, and he thought they could drop the pan and put in a new seal. He had one of his guys, Ray, who works on the older cars, come in for the job. He had to call around to see if he could get a rear main seal and a pan gasket.

I dropped the car off on Monday afternoon with plans to pick it up Tuesday. I stopped by Tuesday afternoon. The engine was out of the car! As it turns out, the cross member prevents the pan from coming out. So out it came. The seal was hard as a rock. Parts we delayed coming from Winnipeg. I picked up the car on Thursday morning.

I was dry underneath while they had it running in the parking lot.

Once I got going around town, I noticed it was leaking, but substantially less. By this time I had to get moving on my 3000 kms drive back to Montreal.

I made it back today. I used about 4 litres of oil for roughly 2000 miles. Which was less than half what it was leaking before the work was done. On day four of my drive, I started to think that the PCV system might be play. I decided to wait until I was home to explore that possibility. It would explain the continued leak.

Thanks to Rod and Ray at Zaran's. And thanks to everyone who offered advice and suggestions here!
